painting FP areas without using UVW mode or a map?
« on: July 23, 2018, 11:18:39 PM »
Hi,
I would know if it is possible to paint on a complex editable poly (on any of its planes, not necessarily parallel to xy/xz/yz) without using uvw mode (as this disables area/object painting).
Creating aux planes and using many  autogrid-aligned FP objects in order to paint in XY surface mode would be very time consuming... I am not sure if I explain myself correctly... Also, unwrapping the editpoly object to use a bitmap to generate the FP is not possible for my scenario... i need to paint vegetation on many surfaces of this fully attached object..
Thanks for any insight.
Regards,

Rokas

Unwrapping would be easiest and best option for this. I wonder why You can't do that?
You do have to use 1st UV channel for ForestPack, but You might put other textures to UV channel 2 .

Thanks!
I understand unwrapping would be ideal but I am not very profficient with unwrapping and the collapsed object corresponds to a 300K polygon object, where there is one unique material, one unique id, and geometry with terraces, external walls, window openings etc (like if had isolated a 4 storey 40m long building to see just the brickwalls and balconies). There are all sorts of things happenning in the facade and even unwrapping to later paint would be quite time consuming...
I am now thinking of  duplicating this object, subdividing it to my desired paint resolution, and  using UV mode on it to cover it fully with my FP. I can then use a paint tool in max to select all parts of meshes I want covered with my veg and delete the rest of this mesh- which will be occluded from rendering.
I cannot think of anything more efficient..

You dont need good unwrap, simple flattern is enough.
Then You can use viewport canvas to paint areas in Your viewport
