How to render SU background images

Hi, so you may remember my scene with the observation room. What I did was stick a big plat piec eof geometry and map an image of a planet to it. Wasn't the best idea..

So any how, does skindigo export the background image too?

Doesn't anyone know what im talking about? Background image? You click on window then style.

You talking about watermarks? SkIndigo does not export watermark images.

Could it in the future. It would be great imo.

If you want to render a background image without using an environment map just put as a plane with the image you want to render set as a RGB emmiter and adjust the power/efficacy until it looks ok.

Out of curiosity how hard would background images/watermarks be to implement.

Not hard...impossible. The SketchUp API does not allow access to watermarks/background images. Hopefully, this will be changed when SU7 is released.

IS it possible to render with a alpha channel?

Okay, I went with ZYXs suggestion and Im getting some pretty decent results.

The floor texture was originally green. Is there any way, I can prevent so much light from flooding into the room?

Uh, and now it refuses to display anything sans backness.. This makes no sense at all..

Reduce the power of your main emitter or/and change the tonemapping of your scene and see what happens.

Hi, I have the same problem (even if I'm not using Sketchup)

I'd like to add a background image (e.g. a City) without adding a "fake plane" that will block the Sun.

Is it possible (in Indigo) to save an alpha plane (32 bit PNG) in order to add the City image via post-processing (e.g. Photoshop) ?

Thank you.

via Photoshop or Gimp, you can extract the Alpha-channel and use it as an alpha map in Indigo, if that's what you meant... (at least, if the alpha map isn't somehow written into the R, G and B channel...)

Does skindigo support alpha mapping?
