broken UVW randomisation.

Seems to happen also even with one single map using displacement:

Checker -> UVW Randomizer (Mesh Element mode) -> pipe to 1. Diffuse, 2. Displacement.

Result is always misaligned. Looks like it has been like this in older versions as well (checked v6.1).


Good Luck

Does the RC1 retains the bitmap node pats after conversion when they are missing their texture?

Thank you. I hope to see this have been fixed very soon.
I cannot continue work with my project (with corona 7). Will try with Corona 6

Update.
Max 2021 corona 6 hf2 seems broken too

We double checked this for Corona 6 Hotfix 2 in both Max 2020 (Render to Texture) and Max 2021 (Bake to Texture) and it works as expected. Make sure the UV Channels and Unwraps are done properly. Also please try with Render to Texture instead of Bake to Texture if you can.

Regards,
Aram

Ooops, yeah, it was the wrong map channel. sorry
But max 2022 corona 7 daily still doesn't work.

Using the Corona 7 Release Candidate - and it seems to have broken UVW randomisation.

One material, multiple maps (although the issue is apparent with just two maps) - both with identical UWV randomisation, in this case by Mesh Element - same seed, same values.

I seem to remember this making the randomisation match on different map channels - so the diffuse / bump / displace / whatever would be coherently randomised across the model - but this doesn't seem to be the case currently, each map is randomised differently making UVW randomise useless if you have more than one map in a material.

Hopefully a straightforward fix to return to the previous function? Nice.

Hi,

I have gone through your issue and it could be that I misunderstood you but according to how you have explained the issue, I am unable to recreate the same misaligned textures using Corona 7 RC 1.

Here is my inspection : https://bit.ly/2TZ6UeF

If you can share your issue with a simple scene or some simple steps which are easy to follow or a small video recording showcasing the issue, that would be great.

Thank you.

Regards,
Avi

Checker -> UVW Randomizer (Mesh Element mode, use U and/or V offset 0 to 1) -> pipe to 1. Diffuse, 2. Displacement. Could also not repro any discrepancy in other slots.


Good Luck

I guess he means multiple bitmaps on same material.

Yes, but testing it I found the above.


Good Luck

Hi Frood,

I was able to reproduce this on my end also. Thank you for bringing this to our attention. I have logged this issue into our system. I hope this will be fixed and implemented soon.

Hello :

Do I need to convert all the v6 scenes to v7 new physical materials?

And would it affects the render time, memory consuming or not
Thank you

Entirely optional whether you convert a v6 scene to the new Physical Material or not. It will have no effect on render time or memory usage (the render time speed ups come from other things). I'd say for a finished scene where you are just rendering out a few more images, probably don't convert; for a WIP scene where you still have work to do, convert, as then you will get the benefits of the new Physical Material in developing the rest of the scene (though you could mix and match old and new if you wanted).

Hi,

So I think that this is caused by having an old version of v-ray installed. Please can you update to v-ray 5 and you should not get this error anymore.

We are seeing if we can do something about this for older versions of v-ray.

Thanks,

Rowan
