OpenGL NormalMaps anti-alias incorrectly...

Using the mac version...

To reproduce this issue:
1: Create a 512x512 texture in photoshop.
2: Launch Filter Forge as a PS plugin.
3: Apply my Space Marines Hardware filter.
4: Re-launch Filter Forge.
5: In Options, change the normal-map baking from DirectX to OpenGL.
4: Click Apply before the anti-aliasing step is complete.

The result is a texture that has bands of reversed normal colors in the parts of the texture that weren't anti-aliased. This suggests to me that anti-aliasing performed while the "Progress" bar is on the screen is somehow different from the anti-aliasing applied directly in Filter Forge. I'm thinking there's some sort of buffer that isn't getting cleared or isn't aware of the changes made to Options.

Apparent workaround: Wait for the texture to completely finish rendering in FF before applying it to Photoshop.

Other notes: I'm thinking this ~may~ be a general issue that applies to all textures with anti-aliasing; it's just most noticeable when you flip the normals. Further experiments encouraged.

Thanks for your input. The post has been moved to 'Bugs and Problems (Mac)'.

Im not sure if it was a one-off, or intentional, but when I used Engraved Delight V 0.2a I had to invert the green channel to get the Normal map to look correct.
