V-Ray considers Corona materials supported

[LudvikKoutny]

Hi,

I am using V-Ray 3.50 and Max 2016, and for some reason, V-Ray shows Corona materials as supported despite not being able to render them. I have combined material libraries for both renderers, and they turn a bit messy because with V-Ray, I see mix of supported V-Ray materials and unsupported Corona materials, even though "Show Incompatible" checkbox is disabled.

On Corona side, everything is fine, V-Ray materials do not show up when "Show Incompatible" is turned off.

I'll make a note about that.

Hi, any news on this? It makes management of my map/material presets and material libraries very messy

We have already logged this into our system and we will update the thread when we have any news on hiding the Corona materials.

Hi,

any news on this? My material library is starting to become unmanageable mess because of this bug

Thanks

I'm not actually able to reproduce this in the latest nightly builds - when V-Ray is set as the current renderer, I don't see Corona materials listed in the materials/maps browswer. Can you give me more specific reproduction steps?

Outside of that though, it can also be a Corona issue. Materials are supposed to report which renderer they are compatible with; if the Corona materials return "true" for V-Ray compatibility, it will be on their end to fix. I would suggest that you report it to Render Legion as well.

Best regards,
Vlado

Ah, I had no idea ball could be on their side. I will ask. I am constantly being able to reproduce it in slate editor's material/map browser. Vray is active renderer and show incompatible checkbox is off. It's not an issue they show in their categories, but what bugs me is that they show in favorites lists or material libraries too.

EDIT: Asked Render Legion, but they say they don't know of any method that materials would decide compatibility with the renderer. According to them, they know only about the opposite way - renderer deciding which materials it supports.

Materials must support the IMtlRender_Compatibility_MtlBase interface, which has a method IsCompatibleWithRenderer() - it allows a material or texture map to determine itself if it is compatible with a particular renderer. For example, all V-Ray materials and textures implement this and example code can be found with the samples in the V-Ray SDK.

The renderer can do this on its end too, but we've never had to do it for any other renderer's materials (Arnold, mental ray, Redshift etc), plus it's not realistic to expect us to add code for all the materials/textures of every engine under the sun.

Thanks, I've forwarded the information to them
