Change the diffuse color over a map assigned with sketchup??

[orei]

Hi my friends.. i've applied a material with sketchup material editor.. and can change the color of that map with the su editor..

but.. if i go to vray material editor.. and change the diffuse color.. anything happened.. the color that i choose.. doesn't affect the model..

So.. the diffuse color become the old color..

anyone can tell me why this??

thanks a lot

VfSU doesn't recolour textures like SU does. It won't even render them properly.

For rendering - don't adjust textures in SU. Instead adjust the textures in Photoshop or similar.

Yeah, honestly this feature isn't supported because of SketchUp's broken and horrible API, so if you want it fixed, you're going to have to get Google to figure out a different way to do the texture colorization, or the way they do textures in general, since that's a mess anyway. We tried to support it, but it's just too messy. You can edit the texture in an external editor such as GIMP or Photoshop, as Thomthom said.

If the material is a sketchup material that has the texture stored in the sketchup scene itself (like the default library of materials in SU), you can right click the geometry that has the colorized material applied to it, and then choose "Make Unique Texture". A new version of that material will be created that is colorized. This only works with sketchup materials that have the image loaded in to the sketchup scene.

This will not work if you're specifying an external image file of some sort for the texture. That's because we write out any textures that are stored in the SketchUp scene, so V-Ray can access them. When the textures are written out, if the texture is colorized, then the written out texture should be colorized. The "bug" where the texture doesn't render colorized, happens because when we write out the textures for all of the materials in the scene, either the colorized texture is not being written out due to another file existing with the same name in that folder, or SketchUp isn't writing the texture out properly so we can use it in the render. So the reason externally referenced textures won't colorize, is simple, we don't write external textures out to a folder, because they already exist on the hard drive. As a result, since we're not writing the texture out through SketchUp, the texture never gets colorized. TADA!

So why aren't we scratching our heads, trying everything in our power to fix this feature? Because SketchUp (as far as I know anyway) is the only application that does this colorization process, so the only place it would be even remotely useful, is within SketchUp. Honestly, there are many other issues on hand that are far higher on the priority list. I'd rather see skewed textures supported than colorization. Or section planes... or... undo... the list goes on. In the end, the colorization that SketchUp can perform, is just too quirky and strange to deal with at the moment. Maybe one day Google will improve SketchUp and fix all of the problems that have been preventing us from supporting more of it's features... one day...

i understood that.. but it sims that in the old version of vfsu when change the diffuse color of a texture that i've aplied by su material editor, the changement affect the scene!!

I ask for this.. because.. sometimes.. i need to use a texture, but the final color result in the render, isn't what i want.. and with this.. i can have a preview of the final result in the material editor of vray..

you can say.. if you do the changement of the color (with colorize texture in su material editor..) you can see the final result in the material editor!! yes.. it is.. but when i change the color in SU.. there are 2 problems:

a) the color switcher REALLY SUCKS...
b) every color changement, affect the wholest material in the scene.. and with a larger model, sketchup hang so long....

if i change the diffuse color directly in the material editor of vray.. i can jump those problem..

any idea??

Re: Change the diffuse color over a map assigned with sketchup??

If you want to "colorize" a texture, just use a blend texture in our material editor, and use an AColor texture in one slot, and a Bitmap texture in the other. That's what we used to do to work around this issue. We had complaints that it wasn't a good work around, and we agreed, so this time we didn't bother putting it in.

The way the rest of the 3D apps out there work (at least to my knowledge), is you would have to edit the texture in an image editor such as Gimp or Photoshop. So I would recommend following the way the rest of the world does this. At least until Google is able to repair any issues that may be preventing us from properly supporting this feature. I know it's not the optimal answer to this issue, but unfortunately that is the answer we're sticking to.

well my friend.. thanks a lot!!!

but.. remember wrong.. or really in the old release.. we can do this in vray material editor?? (i would check on my own.. but need to reinstall vray... and replace the wholest bar in the right place........ )
