Transform causes uvw to stretch.
« on: September 02, 2023, 11:30:17 AM »
Hi. If I use transform to scale any segment, its textures also gets scaled despite using realworld mapping. How can I retain texture scale even after scaling the segments?

Hi,

In some situations - like this one, you might find handy the possibility to map it directly within the RailClone plug-in by enabling the Deform > Mapping > Apply Box Mapping feature. Please feel free to check more detailed information about how to "To Add Box Mapping to segments" in our online reference guide.

I hope that helps.

Best regards,

I've have enabled box mapping for the segment in the deform tab. I think the problem is   transform operator is scaling the segment along with the texture. There should be a uvw map operator that we can add at the end.
Right now I have put a uvw map modifier on top of the railclone object, but this is not a clean solution. Is there any other way to tackle this?

Hi,

In such a case, please try disabling the Display > Render > Use Instancing Engine option to see if there’s any difference (might be, that’s just a partially supported feature in case of your render engine). I hope that helps.

Best regards,

Thanks! Disabling the instancing engine worked. I'm using VRay GPU which doesn't support it.
