Render texture to texture?
show user profile  aniworld
Hi,
I know about render to texture but is it possible to render texture to texture?
by this I mean if I apply a box uv map to an object using a tiled texture can I then use RTT to auto unwrap the mesh and render the texture to it as it was into a single uv map??

Yeah, it's possible.

Probably take longer than just unwrapping a box, though.

I'd recommend rtt at twice the size, then scaling back in ps.

I still cant get it to work right?
so i have a simple box with a tiled brick texture on it (which is scaled down)
when I render to texture and auto flatten the uv's I get a new uv layout over the top of a single tile from the brick texture?
Im thinking I need to use the projection method but i have no experience with this method?

any help?
cheers,

I know I can just unwrap the box, my question was is it possible to take (for example) a simple box place and tiled texture onto it then use RTT to automatically flatten the uv's and bake the texture (as it was) to the new uv layout?
If so I would plan to apply this method to more complex models and save the time manually unwrapping them all.

Your results will not be what you think they will be.

Using RTT's automatic unwrap is no different than adding a UVW Unwrap and using "flatten mapping". The result is THAT is the mapping that Max uses when it's rendering. It will place an "automatic unwrap" modifier on the stack ABOVE your box mapping, rendering it utterly pointless.

No, there is no way to speed up unwrapping. You just get faster at it. If they're that complex and that much of a pain in the ass I suggest you invest in a program such as Mudbox or ZBrush, which handle mapping in their own way.

Thank you Blackmariah for clarifying that for me,
its not that they are a pain in the ass but that I have loads to do :)
anyway I have almost finished them but I just wanted to check for future reference If I was making a bigger job of it than need be.
I guess sometimes you just need to get on with it :)

yea, sounds like your making it harder than it has to be - unwrap it once and duplicate the object, or copy and paste modifiers...
