[SOLVED] Texture mapping issue with ObjectGrass using mesh mask

[paul.chaney]

Hi there,

 

I'm attempting to add grass to the roof of a hospital scene and would like to place it on surfaces using a mesh mask.

 

However it seems that the uv mapping is only correct on the grass polys when using a texture mask.

 

Attached are two screenshots showing the problem.

 

I understand that the number of channels affects how the uv mapping of the texture is set, however I cannot figure out how to adjust the setup to use a mesh mask.

 

Please can someone point me in the right direction?

 

Kind regards,

Paul

Hi Paul,

 

Have you tried to use mesh without UV map at all?

 

Thanks!

I'll try that. Does the UV map of the object surface used as a mesh mask make a difference to the uv mapping of the grass polygons then?

hi,

 

I've just tried this and it doesn't appear to make a difference.

 

The process I'm using is to create a grass object and then apply the mesh mask. When I do this the texture of the blades of grass becomes too large for the grass polygon and the result is I'm only seeing pieces of each texture.

 

Here's a better screenshot.

 

Kind regards,

Paul

SOLVED

 

For mesh masked grass objects, you need to use a grass texture with 4 adjacent variations.
