How do you guys preview textures?

V-Ray V-Ray for Blender General

Since viewport shading is not working, how are you guys preview textures when you are working with vray?

For me I am currently adding a Vray Light Material, an plugging in the texture to preview it, but it’s quite slow.

Hi, I have the same issue. A proper Texture preview mode is highly needed because having to “render” while working on texturing is just a loss of precious time.
I already asked for this before the last Vray/Blender update, but I guess it’s not easy to implement.
Honestly I think it’s a must have before any other feature and I wonder why I don’t see more people asking about this.

Agree, it’s a pain to set up UVs, tiling, and everything, and even lookdev.

yeah i agree. Already created a ticket for this https://chaosvray.ideas.aha.io/ideas/VBLENDER-I-43

In fact I discovered that you can get it by having a “solid” preview setup with matcap and texture.

Really?
Meanwhile Chaos will find a solution for this, it could be a workaround…but I think it’s important to have officially supported for also the other preview modes.

A question: what texture is displayed? the last vraybitmap node selected for that material? And if you have more than 1 UV, it still work?

well, it’s seems to be a bit random. I have some objects with a principled BSDF + Vray Material attached, some only with Vray Material. I still don’t understand what’s mandatory to show the Diffuse Texture. (Testing right now)

ok, so far…

- It seems that when you have Blender Image Texture nodes, you can switch between textures previewed whenever it’s a Principled BSDF material or a Vray Material.
- If you have Vray Bitmaps it seems to preview the last changed texture, whatever slot is used (weird)
- Vray Triplanar doesn’t work at all (no effect)

And this only if you switch to a MatCap preview?

Really weird

Well..this is something I’m expecting..and for those “special” cases, the rendered viewport could be good to use. Obviously, if it will be covered by preview with viewport (not rendered), it will be super.

Hi
Thanks to the comment about the last changed texture being updated I think we might be able to make this work a bit better. This is what I quickly managed to do, it seems to work almost as well as in Cycles.
