Textures in Sketchup and Vray
-
I'm sure this has been explained before, so forgive me if this is the case and please direct me to the relevant post.
I'm certainly a newbie to the black art of rendering. But I'm never quite sure of the correct method of applying textures to objects in a scene. Whether to use the texture panel in Sketchup, or the texture panel in Vray, or a combination of both.
Another issue I've encountered is the problem that arises when you import an object from the 3D warehouse. Many of these (I've found) already have textures associated with them, so when you try to render them in Vray, it produces the error of texture not found.
Upon examination I find the offending textures were part of the object I imported. Then even deleting them does not fix the problem, even if I purge unused textures in Vray and manually delete them in Sketchup.Sorry for such a long winded post, but any help would be appreciated.

Hi Joe,
There's a debugging tool in the vray menu you should try. It's called "Force Sync for All Materials" Try that first. If you are still having issues, you can try the "regenerate all v-ray materials" However, with that option you will lose any vray information you've already applied to your materials. You may want to save your vray material definitions before you try that. (There's an option to "save material" in the vray materials editor window.) Hope that helps.

Hi Andy,
Thanks for your help, that sorted out the stray textures imported with various different models. But I'm still unsure of the correct method of using vismats, they seem a hit and miss affair. In fact I'm finding it easier to use plain texture sets and compile them directly from SU, adding the various reflections, bump mapping etc. within the VRAY editor. Once I have what I want save the vismat, that way I know works.
It seems that many of the vismats found on various sites are more trouble than they're worth...

Yes, you will find that many of the old visopts will not work in the current vfs. The coding has changed significantly since the earlier versions. The current *.vrmat format is in xml format, so if you can open any of the older visopts in a text editor and you can read them, then likely they will be fine. If you open it and find it's code, then it's not likely to work.

I didn't realise you could read them with a text editor, I assumed they were some form of code. Which is seems many of those I downloaded are.
I also think I now realise why they don't work. In many cases the directory path from the original location is set within the vismat. So naturally when I try to use them the location is different and the vismat or Vray can't find the relevant bitmaps.
Luckily many of these textures include the necessary bitmaps, so it seems as I use them I'll eventually build my own library.Thanks again for your help Andy,
Regards
Joe.
