ok, early tests show that this doesnt quite do what i thought it would. i was hoping it would displace the height map when used with an external image. it didnt seem to. it also seemed to have one anomoly at the bottom that i could correct with the distortion control but that then flattened the image. what i was expecting to see were results like crapadilla's mapped spheres shown on this page: http://www.filterforge.com/forum/read...#nav_start but i havent been able to get it to do that yet.

yes, type 3 was what i was looking for.

but the anomoly is coming from a size difference in spheres. take a look at your frame sphere and the profile gradient it plugs into. if you move the frame margin width to 5 it will get rid of the anomoly.

Thanks Kraellin,

I think I've fallen into the usual trap of not trying this with different shaped images. Your image is slightly taller than it is wide, and the frame sphere stops before the bottom of the image.

Your fix works for your image, but unfortunately doesn't work for other images with more rectangular shapes - see attached.

I'm not sure what to do about that. The problem is that the Profile Gradient doesn't stretch with the image, but repeats instead. I think it's a problem that's been discussed here before. Anybody have any ideas?

Thanks for your help,

I was inspired by Crapadelia's renders in the thread Kraellin linked to, so I tried out a few of the nice textures in that thread as bump maps. Techno Fungoid:

ah, you're right! i shld know better. and, yup, just have to use square images for now. hopefully, we'll have something for that in ver 2.0.

and cool on the spheroid images

and changing the bump type
