artzor Posted April 7, 2009 Share Posted April 7, 2009 Hi All, Trying to build a tool which involves having a text object in the viewport. Is it possible to get that object show up in its own image plane and have no affect at all on the default `C` plane? I've made a shader that sends a constant to an image plane, works great. But no matter what i do there is still some kind of output in `C` any ideas? Quote Link to comment Share on other sites More sharing options...
rob Posted April 7, 2009 Share Posted April 7, 2009 (edited) Bundles . make a bundle with your letter in Render ROP :- look at the tab > objects , force objects / force lights , yes thats right delete the * which means all objects , and select you bundle , then the rop will render just that bundle r Edited April 7, 2009 by rob Quote Link to comment Share on other sites More sharing options...
artzor Posted April 7, 2009 Author Share Posted April 7, 2009 Thanks Rob, don't think i've explained myself enough... i want all the objects in my scene to render normally... except a specific (text) object must render only in a seperate image plane and not affect the normal `C` or beauty pass..... problem is that no matter what tweaks i do in vops with alpha/opacity it'll still have some affect, like be in the alpha channel.

If by text you mean texture , why don't you just render an id pass and just fix it in comp. Quote Link to comment Share on other sites More sharing options...
Darric Posted April 8, 2009 Share Posted April 8, 2009 Seems to be working fine for me? An oddity I noticed is that if I send [0,0,0] to Cf in the shader, it doesn't output anything to the "text" channel, but setting it to [0, 0, 1e-09] does. It seems that there needs to be some colour contribution for the second image planes to render, even if it's negligble. Hopefully the 0.000000001 shouldn't drastically effect your "C" channel. Render from the ROP to see it working, then switch between "C" and "text" in mplay. textchannel.hip Quote Link to comment Share on other sites More sharing options...
