HI. I’ve created a jpeg of a light fixture using “save as” from a vendor website. When I import it to my model, the white background is part of the jpeg. Is there a way to delete the background and just keep the light fixture? If it was a component I could click until it highlighted and then delete …

I was watching TV, and my tablet’s charging. Excuses, I know. [image] DaveR: Of course it could be set to not cast shadows and it would look more realistic if the model is sent to a renderer. Why make it look less realistic under any circumstances? In any event, your original reason for sugg…

Yes. Even if it isn’t casting shadows, it could receive them and at least there’d be highlights on the surface that would be more like what you’d see in the room.

How did you know there was a skylight casting shadows below - ha! Not really. I thank everyone for all your suggestions. Will print them out and give it a go - and hope I don’t get stuck at “#1. Select”. I may be back in touch! Thanks again

IrfanView has these capabilities as well… for example, IrfanView’s paint dialog allows dumping a specific color onto an existing color section. Attached is a gif copy of one of the lamp images that took only a few seconds to replace the shadow areas with white. For the brown shadow, the “eyedropp…

Sorry… I missed her original image. Her original only took a single click in Irfanview to replace the background with white, then select white as the transparent color when saving. [image] There are a couple of spots (the ball shadows) that need manual refilling. That means that there is a “gap”…

Hi Dan, I started using Paint.net to remove image backgrounds which is really handy for making plants in SU using images. However, I noticed your familiar with Paint.net and was just wondering if you know if in Paint.net you can add a “transparency mask”, or something like that, to make the image tr…

Use the Magic Wand tool. Shortcut: S Click in the area outside what you want to keep. It will show dotted cut lines and shading for a selection. Adjust the Tolerance bar in the overhead toolbar until only what you want to erase is selected, and the dotted line follows the outline of a plant for ex…

Yeah I can do that ok. I was wondering if Paint.net has an “adjustment” process that makes it so that SU will recognise the transparent layer to save you having to either cut-out the shadow from the image face or use rendering to get accurate shadows. I have a Paint.net plugin ( paint.net \Effects\Tra…

Just had a play with the paint.net plugin. It just ‘adjusts’ the transparency with a slider bar that works bit like in SU. But doesn’t work on the transparent background because it is already transparent I suppose. I actually want to make the background transparent so that it doesn’t produce a shado…

Why make it look less realistic under any circumstances? In any event, your original reason for suggesting cast shadows was increased realism.
