So, I’m starting a new interior scene in Max 2018 Vray RT (latest version of both) and I realise the background plate I almost always use (from a Evermotion scene) is rendering as grey.
But I knew it worked in my old scene - so I go back to the old scene (attached images) - in both 2018 and 2015 (the scene it was created in) - and sure enough, although the scene was orignally rendering fine, it seems like Vray has broken, because the background is rendering flat grey now.
It’s simply a cylinder with a self illumination value of 6.
You can see the old render, rendered correctly, and the quick grab I did after starting it again with what is a later version of Vray.
Could you share the scene here or with our support ? Just the cylinder with the self illuminated material and some simple geometry for the room should be enough.
Also could you write exactly which version of V-Ray are you using now and in which the backplate worked as you expected ?
My sky dome was also just plain geometry but with a VrayHDRI Map mapping type spherical. And this is not rendering with GPU only 3ds max standard.
Best regards,
Olaf
I was curios, tried you scene and had the same bug. (max 2018 + vray rt 3.60.03). But it’s gone when turning off the direct illumination checkbox in the vraylightmtl. Or when using a vraymtl and put the map in the self illum slot with gi on is working here. Seems like a bug.
Best regards,
Olaf
It’s not a bug. It’s just that now the Indirect Illumination toggle is working in GPU and it turns the geometry into a mesh light but mesh lights in GPU don’t support texturing. Just turn the option off and you should be fine (it was always off in GPU before).
I tend to think of things that don’t work properly between ADV and RT as bugs, especially when I am taking assets from one scene to another. Is there any way this can be flagged or adjusted by VRAT RT to avoid this kind of confusion?
