[Help] Shading on flat surfaces

Verrou

But now the ground plane is grey -.-

Turn your ground off in your styles and change your background to white.
You will still be able to cast a shadow on the ground plane.

Verrou

Mine doesn't render shadows

boofredlay

Make sure you have the "On Ground" box cheked in the shadow settings.

Verrou

All my settings are like you say?

Your settings are right and your shadows are falling on the ground plane correctly in that screenshot but I am confused by the preview window. What are you using to make that preview, I don't recognize it?

Verrou

IRender, and also, how do I change the corners of a rectangle/square to a radiused corner?

boofredlay

Oooooh. I know nothing about Irender, sorry. I assumed you were exporting directly from SU.

This Topic should help you with your second question.

Verrou

Na that's a cube, I just want to know how to do step 1 :S

Square (12x12 inches in my example) with radiused corners. (1" in my example)

boofredlay

Ah...

Draw your square. Get your arc tool and select the first point. Drag your pointer to the other side of the square until you see the magenta line and the text "On Edge", then click.

Now move your pointer towards the corner until you see the arc turn magenta again with the text "Tangent To Edge"

Click and you are done.

If you want to make sure your first point is an exact distance from the edge, use the tape measure tool and click one of the sides to start a construction line. Then before you click the second time type your distance and enter.

I hope this answeres your question.

Render engines need something to cast the shadow on. You cannot just "float" in space and cast shadow on something that does not exist at all.

I don't know iRender either but in other applications (like in Kerkythea) you can insert an infinite plane to work as a shadow reciever (something like the ground plane in SU). If iRender does not have this, you can still insert a really big plane whose sides are out of the view and you don't have problems with the plane changing colour slightly against the empty background.

Thanks Boofredlay works great. And i'll just export straight from SU so thanks.

Glad I could help.
