Texture Orientation Hell! please help

[pHANTOMpHREAK]

I am currently testing the newest version of VFSU as a rendering option for the ID department of the firm i am with but i am running into a pretty big problem.

In a nut shell the problem i have is that the render engine seems to be ignoring my texture size and placement. What i see in the sketchup viewport is much different from what the vray render window puts out. My process is as follows:

I finish modelling a blank scene, no textures.

I load up a handful of vismats and begin to dress my scene.

I then scale and position my textures using the texture controls in sketchup (via right clicking on a texture and editing it)

when i go to render my resulting image has some materials ignoring their placement (ie returning to original scale and orientation) and some others not ignoring (sticking to how i set them).

Any ideas as to why this is happening and how to fix it?

This is quite a MAJOR bug for the render engine to ignore texture placement. But i am hoping it is merely operator failure on my part (could it possibly be the specific vismat files?).

Any help would be much appreciated!!

i have attached a shot of a model from 3dwarehouse (stripped of its own materials) with some of the materials i was using, you can see how the back splash tile, chair fabric, flooring and table top have all ignored their placement. (its not supposed to look pretty just an example)



As well here are the versions I am using:

vfsu - 1.48.98
su - 7.1.6860 (don't like

Have you applied those materials inside (editing a group or component) a group or component? remember to put your materials on the front face inside sketchup (not the back face). Don't apply your materials outside a component or group.

And lastly, we can't blame vray for sketchup for not following the texture mapping inside google sketchup.

VfSU, and other render engines has problems when a textures in SU has a distorted form.

But your example doesn't seem to have such effect - I see no reason to why it should be like that. As artu said, it could be some issue if you applied material to the group instead of the faces inside. (Though it shouldn't be like that.)

Got a sample model to share?

yes it shouldn't be like this. scaling/editing inside su model space usually works for me.
as thom said, OTHER RENDER ENGINES has problems when using textures in an unusual way in sketchup

Note the issue is only with distorted textures. Materials applied to Groups and Components should work.

Also don't use the repeat and rotate option inside the V-Ray texture editor. You could have some difference between the viewport and the render. For ex. if you rotate the texture 45 deg inside the V-Ray material you are going to have something similar to your image.
