Here's the result of the similar set up in Max, I left the light materials visible directly. The one on the left casts GI, but no reflections, the one on the right reflections but no GI.

EDIT For those who don't want to download the C4D scene, attaching the result - both light materials continue to cast GI and show in reflections, even with the relevant checkboxes unchecked.

Yes, it's not working as expected.

In your scene btw:

You have lights with the Corona Light Mtl applied. You should just have regular geometric objects, not lights :) In this instance, two planes, with the CoronaLightMtl applied. Using a Light Material turns that geometric object into a light source. It should be one or the other - a Corona Light, or geometry with a Light Material applied.

Then the Specular only light material should have Emit Light unchecked in the Emission tab (as you don't want it contributing to GI). This should stop it casting light into the scene, with the Advanced tab keeping it showing in reflections and refractions. However, unchecking Emit light does not stop it emitting light at the moment.

The Diffuse only would keep Emit light checked, and have the other options in advanced unchecked. Again however, unchecking Visible in reflections for this material is not making it invisible in reflections like it should.

So at present, this is not working as expected, even with a correct scene setup. Attaching the scene as I'd set it up (just used spheres for the geometry rather than planes, but could do it on any object - there's no performance penalty for using geometry with LightMtl applied vs an actual CoronaLight), even though the scene is not working as expected at present.

PS - C4D R19, Oct 13th build of Corona.

I'll take a look - I am not 100% sure that the LightMtl Advanced features are working as expected based on some of my earlier tests, as I was getting different results in C4D compared to a similar set up in Max. I will let you know shortly what I find with your scene too! Thanks!

Jobs / Re: Looking for Corona Training

« on: 2017-10-16, 15:29:50 »

No online training - the depth and content of the Academy training is such that it needs to be face to face, and we need that also to confirm that everyone has grasped the concepts in order to certify them. For online training, our focus is on our YouTube channel (https://www.youtube.com/CoronaRenderer) and on our helpdesks (https://coronarenderer.freshdesk.com/support/home for 3ds Max, and https://help.c4d.corona-renderer.com/support/solutions for C4D).

If ever you do get a chance to visit us in Prague, that would be awesome! Also, as more people get certified through the Academy, there will be more courses offered all over the world from certified trainers - those courses are also listed on the Academy website, like the SOA course which is listed on the Academy home page taking place in Italy in December, along with a list of Certified Trainers if you want to contact any near you to see when they might be planning on setting up a course https://corona-academy.com/certified.

I hope something here proves useful!

Aha I see what you mean now - I never use Render View myself (I use a Corona VFB on my second monitor for quick preview renders, more than ever now that IR is working, though that doesn't work with volumetrics at the moment unfortunately). Now I know where you are rendering, I can confirm this, same happens here - first use of Render View shows Volumetrics as expected, but stopping it and restarting the Render View does not show the volumetrics. My tests on a PC, C4D R19, Corona Oct 13th build.

TY for the report and follow up info!

My bad, just realized that in IR the override isn't showing at all - it was actually showing the HDRI environment background (used as the Sky)!

[Max] General Discussion / Re: Node minimum requirements

« on: 2017-10-13, 18:49:08 »

On render times, there will be some overhead for the nodes to receive the files sent across the network, but that's usually small compared to render times, so pretty much adding a node with the same processor as the main machine means you can render twice as fast, give or take.

As for how many nodes, two things there - a standard Corona license allows for one workstation and 3 nodes, so if you want 4 or more nodes you will need to purchase the extra node licenses. And then the more nodes you have, the more network traffic there will be and the more that will become an issue and you may need to look into specialized network setups rather than just a standard "home router". Several users on the forum have got those set up and could comment more on that. I just use a regular home router to run 1 WS and 2 or 3 nodes at the most.

[Max] General Discussion / Re: Node minimum requirements

You are right about the graphics card, it would be redundant on a node for Corona, so you can go with onboard graphics or a low end card (just in case you ever need to plug in a monitor to work on the machine directly vs. accessing it remotely from the main workstation).

However, memory would not be redundant - nodes are best to have the same memory as the main machine if possible, as otherwise something might render on the main machine but not on the nodes because they run out of RAM. Nothing will "break" in the technical sense, DR and Backburner will still work if nodes have different amounts of memory, but if you try and render a scene that needs 64 Gb of RAM and your nodes only have 8, then they will run out of memory and contribute nothing to the networked rendering.

I do have 64 Gb on my main system, and 16 Gb on my nodes, but I don't render any heavy scenes so that works for me as all my renders need less than 16Gb so I am fine. That is likely pretty rare though, especially if doing any full-scale arch-viz work for example :)

Hi Flamingo!

I don't know the cause, would have to leave that for the developers :) Just wanted to have as much information as possible on how and when this happens, as that can sometimes be critical to finding out what is going wrong, ty for that!

I've not been able to duplicate it here so far, also using R19 on a PC, with Display set to Gourad Shading. Is it every scene and every material by the way? Corona Materials, and does it make a difference if they have bitmaps applied, or bump mapping, etc?

Don't forget if you can replicate the original crash, the bug report text would be useful for our developers. Thanks!

I'd need to know how you have things set up. Also, is that in an offline render, or in the Interactive Rendering? For sharing the set up, you can post screen grabs, or just post a cut down version of the file, or if the file is private in any way, you can use the private uploader at https://corona-renderer.com/upload

Thanks!

Not able to replicate this here, on latest build on a PC in R19. Flamingo, are you on Mac or PC? Which version of C4D too, for both users having the issues.

Also, in case it plays a part, how are you applying the material? Is the object selected and you use right click apply in the material window, or is the object not selected and you drag the material from the material window to the object manager to drop it on? (And does it make any change in the behavior if you do it the other way?) What Display settings are you using?

Global volume, when using render view seems to only be working if i have the volume material window open, and change the absorption distance value...

If you mean in an offline render (global doesn't seem to be working in IR), it's not a bug as such as the Absorption distance in a Corona Volume material starts at a default of 0, which would indeed give no effect in the rendered scene. This is the same in 3ds Max, and most likely by design as the actual distance required will be unique and wildly varied for each scene, so there's no "good" default value and best to set it to 0 to encourage / remind people to set a value that works for that scene :)

Let me know if you meant something different, though! For example, once you have set an absorption distance, there's no need to keep the material window open, as it would be a bug if that was happening for you (it isn't happening here).

Just a note on the status in my tests today - Frontal projection can be selected, but doesn't work. In an offline render, all I see is a blur :) In the IR, interestingly, I do see the image, but it is not showing the full image, rather like it has zoomed in to just one part of it.

If I load a bitmap direct into the shadowcatcher Backplate slot then it looks as expected. If I load a CoronaBitmap in there with the same image, it is upside down. Thanks!
