Hi
Looking for help regarding bercon tiles and corona. When ever i use bercon to create my tiled floors or walls, i can never get a bump from it.
I generally use these setups
bitmaps > multitexture > bercon tile > diffuse
bitmaps > multitexture > colour correction > bercon tile > bump or displacement
so with that in the bump, nothing happens at all. if i use displacement, it says calculating displacement and then the PC slowly starts to lock up until it freezes and i have to turn it off. this generally seems to be the case for displacement on any material, so i tend to avoid displacement completely.
i would like to know how other people get a bump while using bercon tiles with corona.
thanks
-
Looks like in daily builds it does work with displacement, but does not with bump. Maybe it's the same for you, and the displacement is crashing because it takes up all RAM.
-
OK so i have to use displacement to get a result with corona? or is this the case with most renderers and bercon? how do i stop it from using all my RAM? it feels like it just slowly begins to eat at the PC until the cursor freezes and then im stuck...
thanks for replying
-
There are currently some limitations for multitexture+bercon, for example it does not work with IR.
If displacement is eating all you RAM you can try:
-moving the object farther away from the camera / camera from object
-changing displacement settings (render setup > performance > displacement), increase screen size
-optimizing the displacement material - if it's very detailed, I would suggest blurring it a bit - of course if it's even an option
-
OK, the displacement was a map made from the bitmaps being used in multitexture but i also tried just using bercon tile by itself with black n white no extra detail.
I'll see what happens if i change some settings
-
Tried upping the displacement number in settings, it didn't crash but didn't give a result any where near acceptable. I dont think displacement is going to work, I have 16gb of RAM on this machine, which has never been a problem before with displacements on other renderers.
Just downloaded a trial version of vizparks walls & tiles, it also uses bercon but with their own custom material node and map nodes. Again I am still struggling to get any kind of bump from corona. Going to contact them directly as well, as it says corona is supported, it even has a singled out material just for corona use.

Displacement works out of the box. Bump works too, but with some modifications and limitations.
Luckily, bercoin maps didn't crash max this time. Sadly, it's quite rare experience with those otherwise marvelous maps.

Hi Romullus, thanks for your response. Now you have bump working for each bitmap that you have dropped into multitexture but you dont have the bump between each tile. so im using bercon to make bricks and need a bump to define each brick, as well as a bump on each brick.
Displacement doesn't seem to work for me, i just ran it on another machine. 4k image with displacement set to 3.0 in setting. it used 30gb of ram and looked awful. it didnt follow the brick pattern at all and for using 30gb of RAM it was a costly render for a not worth while result.
edit- also interesting you use an output node, what exactly is this for?
-
You're right, i've managed to make Corona render either gaps or bitmaps in tiles as bump maps, but not combined result. But bump mapping is always a bit finicky in 3ds max. OTOH i don't see any problems with displacement. I've plugged same map into displacement, set screen size to 1 and at 1600x1600 resolution max peaked at 3,5GB RAM usage.
-
Is it possible that you could send me a sample scene with the displacement etc all setup and i try to render it on my machine? my displacement didnt get anything near a result like that. If i can get it to work like that, problem solved but for a herringbone paved floor it was using 30gb of ram and doing random things as a result.
It would be good to figure out what is wrong my end.
-
Sure, attaching max2011 scene.
edit- also interesting you use an output node, what exactly is this for?
It's just bump multiplier. By default bump in bercon tiles are very weak, so i pluged output map and increased bump output there. Same effect can be achieved in bercoin tiles map or by increasing bump amount in material itself though. It's a matter of habbit :]

As far as I can remember, VizPark updated their stuff to have Corona versions, but there was a bump/displacement issue due to their coding/script. Not sure if it was ever fixed. They post here but I heven't seen them in quite some time. Here was the thread:

Yeah i actually had an email conversation with Martin about the displacement and bump.
Regarding that test scene, it rendered fine on my machine but as soon as i try to use it in a more populated scene it doesn't work and i quickly use more than 16gb of RAM followed by the PC locking up completely.
Does the amount of geo on the plane effect how the displacement modifier or material works? if i subdivided the ground would it ease the calculations at render time? or am i just limited by the machines RAM?
my scene uses 1.5gb of ram then when i hit render its well above 16gb before the calculations are over. maybe my ground plane is too large, it could be calculating things not in view of the camera? or that is hidden behind objects? thought i thought it was screen based and so, sometimes more efficient?
its hard for me to test because each one normally ends in a PC restart each time. I'm going to try a few more things with the test scene and my scene.
-
Progress was made this morning! i cut up the ground plane for camera views and the displacement started to render properly. It still pushes me for RAM but im actually getting a result! Thanks for the help guys. It's good to be seeing some results

Hi,
I'm having issues usign Bercon Tiles to generate bump maps. Absolutly nothing happens ... I'm using the last dilybuild. Can you confirm this ? Is there a fix to be made ?
Regards.

Can you tell us more about the material setup? Some screenshot or a sample scene would be great.

Hi guys!
It's seems to me I found the way how to make BerconTiles work as bump map.
Here is my approach. BerconTiles works differently in diffuse and bump slots, so I attached max file so you can check how it's done. Important things for bump map marked on attached picture with material settings.
Hope you'll find this helpful
-
Here is a screenshot. I tried changing to Color #2 (as explained by Bormax) but it didn't work ...
Don't know if it's linked to Corona or BerconTile ... I can get the joints working when linked to the bump slot but the texture never shows up :/

Hi
You missed part which I've marked now with green and yellow colors. This is the part which makes joints to work as bump! Marked by yellow line is the same BerconTile map but without any textures in color slots. Blending mode in Composite map must be set to Multiply.
You can download max file and check everything there - it's attached to my previous post here (bercon-tiles_bump---max.rar - I renamed the archive :))
-
The really good part would be a native material function that WORK all the time.
-
Agree, advanced CoronaBump map is very wanted feature.
-
I wasnt talking about bump, i use bercon tiles every day at work, i know about walls and tiles plugin, but it uses the same bercon tiles, right now the bump and displacment is broken, and i dont trust in the relfection using the same bercon for the same reason, im just stuck with no other option.

Displacement works but it uses alot of RAM and sometimes you need to set it to 1px instead of 2 to keep edges clean. Bump is where I could never get a result so i swapped to just using maps and photoshop. Though even without bercon Corona bump doesn't always seem right.

Did somebody try to render picture from my file? Does this way of bump mapping using BerconTiles works only for me?

Sorry my reply was about when i originally started the thread, just saying that displacement did work but bump was the problem. i gave up after that.
I'll try it today though with your file.

Tried it the way you explained but still doesn't work :(
I'm about to try your file.

Using the same method as previously I've made this brick wall. Maps for bump are just randomly cut out separated bricks from brick wall texture (they are not good quality, so I don't like how they look as diffuse map), but if you have set of prepared diffuse/bump/specular maps you can get better result. Geometry used here is a simple box. On pictures you can see how this box looks with bump map only, with bump+reflection maps, and with bump+reflection+diffuse map.
-
What Daily Build are you using? I'm using the very last one.
I just can't make the texture bump working, only the joint does work, even with your file.
Regards.

I use daily from 2016-08-05, Max 2014
You can try to use Output map and increase Bump Amount value there, like I've done it here. In this example Bump Amount = 40!

You're not alone Alexandre, we're having the same problem here because it's integral to Walls & Tiles. Super frustrating, would really wish there was an alternative to bercon.

Glad (well, not that much uhuh) to hear that from you.
Someone from the dev team can tell me/us if it's a BerconTile or a Corona Dailybuild problem ?
-
Rejoice! So for those of you that use walls&tiles with crossmap, I figured out how to get all the bump maps to work with bercon and give you custom brick shapes.
I haven't tested this without crossmap, but i don't see why it would work with other multitexture plugins.
One important thing that isn't in the attached material breakdown is that the texture blur value needs to be .01 for all the crossmap nodes.
Let me know if you guys have any questions.

Well i've tested a bit around... as i constantly had struggles when working with bercon-tiles and Bumpmap.
Realized its somehow related when working with - real-world-scale / real-world-map-size.
Tested it with that tile-scene from bormax (#16) - it worked in my scene-setup (units-cm) ... but when i set his mapping to real-worl-scale it got messy, and tiles didn't show up anymore.
So i tried a bit around with lots of errors...
finally came to an result... had to insert a corona bumpconverter-texmap into it and raise strength by 10-to 25 ... and increase bump value to 10 ... to get a similar result as plugging a bitmap directly to "bump value 1"
it gets more complicated when using corona-normal-map with a normal-bitmap from bercon-tiles ... as it works quite well with standard values... so material-bump-level1 and in coronanormal "strength - 1" at the normal map.
when adding additional bump...then you got to increase strength value by 10 and have an corona-bumpconverter-textmap with value around 10-25 before that.
when working with no real-world-map size... bercon tiles and bump works quite well.
took me years to figure out :( why its not really working... also don't mess with blur-value in coronabumconverter ... at least when its to low, its not working either again.
finally found a day to test around why it never behaved like i expected it
