fxrod Posted March 16, 2007 Share Posted March 16, 2007 Hi Everybody! I'm using a cookie sop to fracture geometry that has already been uv'd. This leaves me with interior geometry lacking UV information. I have been applying the uvs using the UV Unwrap SOP to the pre-fractured geometry, since I'm applying the UVs procedurally and it's okay that my textures tile. The bad news is that I have not been able to come up with a good way of applying uvs to the interiors without there being obvious seams. I can apply a unique set of uvs to the interior geometry by using a simple orthographic projection and orienting the uv projection plane to the bounding box of the object. I'm sure this issue has come up before. Any ideas or suggestions will be welcome. Thanks in advance! Francisco Rodriguez Quote Link to comment Share on other sites More sharing options...
edward Posted March 16, 2007 Share Posted March 16, 2007 I haven't looked but does the Fracture example on the Exchange handle this? http://www.sidefx.com/exchange/display.php...amp;pagesize=10 Quote Link to comment Share on other sites More sharing options...

Your propbem is "How to get a unique set of uv, right?" In my case, I'm using maya shatter effect. (suggested that original fracture geo has already uv...) I think side fx's fracture otl has some problem in some geometry... Anyway, make fractures in maya then bringing back to houdini as obj file. In UV view, slecet connected primitives (hotkey '7'). Now You could group them separately. Quote Link to comment Share on other sites More sharing options...

In the example, a procedural shader is used. In our case, we will need to use texture maps, so we are looking for a solution where we can procedurally apply UVs to fractured geometry. I included a .hip file, if you have a moment to look. Thanks! cookieExample.zip Quote Link to comment Share on other sites More sharing options...
