sorry, i fogot to give you the actual node http://dl.dropbox.com/u/1484680/GRP_SphereMapping.ms http://dl.dropbox.com/u/1484680/GRP_SphereMapping.sfx copy both files to 3ds Max root\Scripts\ShaderFX\Nodes and it should work
thanks arrangemonk, however when I try load the file I get the message 'file did not load correctly due to missing node(s): SphereMapping do I need another file to go with it? cheers!
http://dl.dropbox.com/u/1484680/spheremap.SFX did a spheremap node once should do the job shaderfx cant convert from tangent to view space first you have to convert to modelspace then to viewspace then add 1 and divide by 2
Thanks for sharing this, arrangemonk. With your permission I'd like to alter it so that it supports an incoming normal socket (instead of using the normal from the surface vector node) so that it can be used with normal maps. I'd like to include the altered version in our next update of ShaderFX. Is that OK with you?
I dunno ace I had a look on their forums and posts from 2006 suggest they've never had sphere mapping apart from the example file (which uses custom code rather than a node I think?). btw, does that example file work? am I just using it wrong somehow?
