Title: Render Light spots issue
Post by: aliyahsavannah on 2014-12-22, 03:49:02

This is a Bedroom render of Bella View. How can I remove the light spots from this scene? I attached the render.

Those looks like reflections of light sources. Can you show curtain material setup screen?

I think romullus was right.

You have a reflective material, if you want diffuse secular reflections use a very low glossiness value, like 0,1 or so, with 0,5 you may get visible reflections, plus use a lower reflection value, like 0,25.
Also why do you use a 2,0 value for ref IOR?


I think that could remove the reflections.

Cheers!

As I am new to corona and other render engines.  I am learning based on feedback and experience. You are correct. The IOR of 2 is too high. Modification have made. I am pulling real life objects from the Internet, comparing materials and ways to improve my skills.

Thanks for the feedback!
