8-bit Gradient Bitmaps result in noisy/lumpy renders

[alexyork]

And converting that 8-bit TIFF up to a (faked) 16-bit TIFF makes no difference either. Still lumpy.

Well, at least that prooves that difference is in the file itself, not only in the way Corona treats it. Now the last step would be to try to render those two files in other renderer and see what its outcome would be :]

Hah.. .well, apart from Scanline we don't have anything else here. I've sent the map to the corona guys so perhaps they can take a look at it.

Moving back to bug reporting. We will look into this.

Update from dev team side: We have tested the uploaded 8 bit texture in different renderers in bump slot and it gives the same "stair case" look, no lumps are visible.
The lumps may be the result of the additional nodes that are used on top of the texture.

Cheers. I'll see at some point if I can figure out if that's the case.

ok, moving to resolved unless the bug is isolated
