maintain uvw
« on: August 05, 2021, 02:38:13 PM »
Hi. See attached image.
I used 3d max advane wood texture.
Without uvw modifier on the object.
Notice the top of the stump. Fp does not correct the UVW texture.
How do you solve this?
Thanks

Hi,

This happens because the Advanced Wood map is a 3D texture that is centred using an object's position and orientation to calculate the map. This makes sense when it's applied to a single object, but when you apply the map to a Forest Object it takes the entire scatter into consideration as a single object and the coordinates, therefore, don't look correct. Basically you would get the same mapping issue if you collapse Forest Pack to a single mesh.

There are a couple of things you could do to work around this limitation:
1 - Instantiate the Forest object using Forest Tools. This would convert the scatter to standard Max instances that would be compatible with this map
2 - In Forest Pack 7 you could enable Non-Geometric Object for the item in the Geometry rollout. This is a bit of a hack that will use a different instancing technique designed for lights and other non-geometric items. It should render fine, butbe aware that viewport displays will be affected and you won't be able to use Forest Colour.


I hope that helps,
Paul
