Title: RoundEdges shader
Post by: ofengestalter on 2019-01-08, 08:43:54
Does anyone know how "RoundEdges" work properly? Or is it not ready yet? Thanks

What exactly seems to be the problem? How are you setting it up?

use that in bump channe and set the radius....!
it works fine.

Thanks. I did it as you described.
But it doesn't work for me.

you need to apply the material to the cube.

Pretty much that, you need to apply it to a cube :) Also, I've noticed that the IR doesn't update properly with the RoundEdges shader so thats a bug and you'll need to restart the IR each time you make a change.

In my experience the default radius of 10 cm is way too large and gives you weird looking shading. Set radius to about 0.2 cm as a starting point.
Set your material preview to cube to see the effect without IR.

LOL  Thanks. I did it but somehow it doesn't work either

Probably best to share your non-working test scene. That way someone can comment on exactly how to fix that particular scene, and you'll be able to figure out what you were doing wrong from that :)

Ok. I try it on my Mac too.

This is what I get on my PC.

Good idea. attached you'll see the file with the nonworking setup. Thanks for looking in it!

The round edges effect won't be very visible with just diffuse and a generalized light source. The Round Edges 10cm actually has the rounding set to 1cm.

If you enable reflection in the material, the effect will show up. I'd say a value of 2 or 3cm might work best at this scale. Attached is an image where I made the 10cm actually 10cm, and enabled reflections for the materials - you can see that 1cm is too weak (the middle cube), and 10cm too strong (the farthest cube).

OK. Thanks. This is by far not what I expected. Not to compare to the V-Ray Advanced Material with the "Round Edge" in it. I am a bit disappointed from that RoundEdges now and have to bevel the edges from the model.

Actually, beveling should look just the same with that kind of light source and material (that is, with no reflectivity). Would be interested if the result is any different :)

Hi Tom.
You see the beveled objects in the back. (same amount as the corona round edges)

in this video it looks certainly way better...
is there something wrong in the setup?

i scaled all down, 20x20x20 cubes, with rounding 0.5, 1, 2cm
looks a bit better, but nowhere like in the video

for me it looks a bit like something is broken with the roundshader.
