Hey does anyone know how to get rid of the sort of splotchy lighting/shadow that comes about every now and then when you render a daylight interior rendering? I have it on a high 300dpi setting and I'm getting really unsmooth shadow and light.

Post your render settings along with an image of a "bad" rendering you are getting.

I could be wrong but it looks to me like the "splotchy" look you are seeing in the image is just a material texture map on certain materials in your project. the shadows actually look really smooth.

I'll see if that might be the case but I don't believe I have a texture on the walls

That's the problem.... default. Add a material then render.

I checked my materials and there's no image or bump map assigned, it's just a color, no gloss or anything and somehow its super splotchy all over it. It seems like its the light and its going through rippled glass or something like that. I checked my glazing on the window and it all seemend fine. Thanks for the suggestions but anyone have any other ideas what it might be?

Just in case anyone was curious to know, I found a solution to the splotchy light that I was getting. It turns out its a fault in the metal ray render engine with the final gather and photon settings that it defaults to. Since we can't access those settings within Revit like we can in Max the solution is to up the Indirect Illumination Smoothness value in the advanced render settings.

Did you try a different material all together on the wall?

Yeah, I varied it to a fabric, just the "generic" gray material, and tried a material I've used in the past that rendered ok with all the same settings and all of them came out with the splotchy sort of effect on them
