I'll top it.

Instead of respecting it I'll add a checkbox in the processing tab of every layer, so you can un-premultiply separately (by the alpha channel in all cases).

Since I like to pick the nit: Actually it is not the alpha channel that is unpremultiplied, but the RGB channel that is processed.
Basically the colour is boosted by the difference of the current alpha value to the alpha being 100% opaque.
This in turn allows a compositing app to multiply the RGB by the alpha value and get the original colour.

I'll try to add it to the next release.

From my recent experience with Shake, it seems that even if in LW the 'unpremultiply alpha' is selected, the alpha is always premultipled. It would be nice if exrTrader respected this setting

Hey, me might just do that

Thanks and have a nice week end!

Sure, no problem. Hope it can help get the word out. 

Thanks a lot *blush* ... can we quote you on that ?

Thanks for the suggestion with "Object Tangent" works beautifully. I really love infinimap, it should be on every Lightwave user's "must have" list. The new openEXR support is sweet, giant 32-bit floating point images with a small memory footprint!

Agreed, I wish that was possible. It would have also saved me from coding the 80% of infiniMap that emulate LWs image texturing
That output actually interprets the infiniMap image as a bump map and outputs a vector that perturbs the normal according to the bump.

You can try the "Object Tangent" node from Denis: http://pagesperso-orange.fr/dpont/plugins/nodes/Additionnal_Nodes_2.html , this works if there is a UV map to project the normal map with.

P.S. native suport for normal maps is on the to do list...

In my never ending quest for larger (poly count), more detailed geometry in Lightwave I've been playing with normal maps. I'm wondering if anyone has come up with a good work flow for using infinimap to load a super large normal map and apply it to a model. I'm stuck because its seems lightwave's "NormalMap" node does not take any image input.

One way to solve it would be if or is there a way with infinimap to make an image loaded by infinimap appear in the image dropdown list so that I could select in in the normalMap nodes image dropdown.

Or I've been playing with the infinimap extended node thinking the "colour (Normal)" output might work somehow, but I still seem to be stuck in the fact it needs to pass through the "NormalMap" node which takes no image input.

Any suggestions would be appreciated. Thanks

Hey, that's good news, congratulations!

USB seems to be performing a lot better. The Macs were still running fine this morning. Strange how the Linux nodes have never caused this much trouble
