Hi Everybody!

Please, could you give me an advise as how to remove the speckles appearing on the edge of a wall while making interior render. With the time process they get more and moe, firstly randomly spread along some walls eges, they progress till making a real dotted line on the wall edge. This appears only in packet mode and when the sun and sky light sources are on. Sorry for being unable to post an image right now, but will do later to make the issue more clear.

p.s. I read here on the forum some steps to avoid this effect but none of them worked for me.

I changed the wall material to glossy, then turned on " no light source reflection", then lowered sun highlight setting to zero - all with no success.

Thanks in advance for any help :)

  • My problem is similar. The difference is that the positive corners also mean a huge amount nennyiségben. Other than rendering it no problem (vray). I like the NXT because it renders a nice job, but with this problem I do not know what to do. The entire model can not edited. There is not time. I can somehow be avoided? : (

    Thank you. Tom

  • If the geometry is rectangular and perpendicular, there is usually not a problem. But if any of it is at an angle, then light can slip through.

  • Al, Thank you so much!

    How I did not realize earlier that incorrect geometry might be causing this speckle effect ?! :)

  • Thank you for sending me the model. The problem was that you wall sere only a single face think and light was leaking between the edges of the walls.

    I went around do the back of the house and made each of the walls think - by adding a new face on the ground and raising it up the the height of the walls. And I had to do the same thing for the ceiling. That seems to have fixed the problem.

  • See if you can make a small model for us to demonstrate the problem, and we will take a look at it.
