Steve:
raxx Here's an Anim8or project with 4 Reference Images using all 4 combinations of (Transparent/Non Transparent) and (Alpha = 1/Alpha=0.5). The image is a .gif file of a target with a transparent background, which show as transparent when the Transparent box is checked.  When Alpha is 1 the target is opaque and when it is 0.5 the target (and background in the image, if visible) are partially transparent. I think everything is working correctly here.

As for the values of alpha < 0 and > 1, I usually let parameters go outside the expected range because people have come up with some very interesting materials using negative values and values >> 1 for Ka, Kd, etc. including some interesting toon shaders. On the other hand it probably doesn't may sense for values like alpha to be out of range.

My graphics card (also Nvidia) does the same as yours so I guess that's how it handles it.

Claude:
Tell me if out of order here, but in the case of the jpeg, is it possible that the fragment shader actually samples the non existing  alpha channel of the RGB texture when  Transparent is checked ?

Shouldn't the option be disable anyway when the texture doesn't
have an alpha channel ?

Steve:
Claude, thanks, that very well may be what's happening. The alpha channel is supposed to be defaulted to 1.0 when the image file doesn't have alpha but it just may never have been used in this way before. I'll look into it.

Some small feedback:
CAD Mode doesn't show length for each line
CAD dimensions seem to be using screen coordinates, but should be using world coordinates?
When clicking layers, if layer 7 is hidden, and you click layer 0, it still will select points from layer 7.
Reference images no longer show up in wireframe mode.
Environment mapping doesn't show in realtime using OGL, only during Render, even with shaders enabled.
ART ignoring diffuse color shading on greyscale textures.
Window title seems to just say Anim8or, I think it used to have actual titles.

Steve:
SubDrag: Thanks for the excellent bug report :)

CAD Mode doesn't show length for each line: I'm still deciding what to do here, but there will be something along this line. Showing all the line lengths gets way too cluttered.

CAD dimensions seem to be using screen coordinates, but should be using world coordinates? Can you give an example? I think that the coordinates are world coordinates.

When clicking layers, if layer 7 is hidden, and you click layer 0, it still will select points from layer 7. Yes, there are still some selection bugs associated with layers, such as Select All selects locked and hidden objects. I'll fix 'em.

Reference images no longer show up in wireframe mode. Should be fixed in next drop.

Environment mapping doesn't show in realtime using OGL, only during Render, even with shaders enabled.
ART ignoring Cube Map environment maps work in all rendering modes, but single image environment maps are only supported in the software and ray trace renderers. I'm working on using GLSL for the shader language instead of assembly which will make it much easier to support this.

grayscale textures Strange bug, can you post an example?

Window title seems to just say Anim8or Thanks, I hadn't noticed. I'
ll fix this.
