Regarding the aspect ratio, I need more information from you to be able to reproduce this problem.
On your screenshot I can see that the people on the far right are tiling twice vertically.
Please go through this step-by-step procedure and let me know what you do differently:1)
I create a 1,256m x 2,020m plane which faces the front view in SketchUp.2)
I create a new material, make sure the Lock Aspect Ratio (the chain icon) is on and add the texture (your 32-bit 1256 x 2020 pixel DDD file converted to TGA and/or PNG format since SketchUp doesn't support DDS).3)
I apply the material to both sides of the plane.4)
I adjust the texture so it reaches all 4 corners of the plane (Right-click on the plane -> Texture -> Position.5)
I export the plane to DAE format with all export options turned off apart from:
- Triangulate All Faces ON
- Export Texture Maps ON6)
I import the DAE file in Lumion SP2. The plane looks just like in SketchUp with transparency etc.
At this stage you can either investigate the aspect ratio problem or the billboard problem:7A)
To investigate the aspect ratio problem when replacing the texture, I try to apply a Standard material, and replace the imported texture with a random texture with an arbitrary aspect ratio. This works as expected (the new texture stretches to all 4 corners of the plane).7B)
To investigate the billboard problem, I apply a Billboard texture and the resulting bug, i.e. that the plane turns white and fades out as the camera moves away, has been reported on the internal bug tracker list as described in my post above.
If you do anything differently, please provide us with a more thorough description broken down into steps, so we can reproduce the problem
