what's this?

i cant figure out why this happens, does anyone have any ideas? those weired spots i mean

Re: what's this?

try assigning different material to see if they still show?

Re: what's this?

are you using light source. i think untick the affect specular if you are using light source.

Re: what's this?

no i am not using that, on monday i will see what it is, i am using version one of vray stil my friend

[nomeradona_cg]

Re: what's this?

old version has also omni light and rectangular light right? so im asking if you are using one of them. my suspicion affect specular was ticked and the specular of this light source is showing... just a guess since we dont have your model.

Re: what's this?

i am not using any omni lights just rectangular and they dont have the affect specular option

Uploaded with ImageShack.us, the problem is everywhere now in my model,see whats happening,how is this happening? any solutions?

Re: what's this?

Can you show us your setting? Maybe upload the scene? or send me the scene to my email.

Re: what's this?

the model is a really big model, 91mb, can i send you the file then the maps folder separately? am using sendspace

Re: what's this?

one addition my friends also have seen this problem and me before on previous models, couldnt find the problem, i really hope we find a solution FPEDROGO

Re: what's this?

i sent you the link fpedrogo, what have you observed so far?

Re: what's this?

I have to double check, but in my test the problem was the low irr map solution and the color mapping. You have -5 -3 for the Irr Map, this is very low solution so you will have a lot of really big blotchy. On the HSph Subdivs you have 30 and this is very low too. Also you are using exponential on the color mapping, this is not bad, but the problem is the bright multiplier that is very low. I don't remember, because I'm at home, but I guess you have 2 or 3.

To resolve the issue use IRR Map -4 / -1 and increase the HSph Subdiv to something between 80 - 120. In term of the color mapping, I always use Reinhard for the color mapping. Reinhard is the best solution, because is a combination between Linear and Exponential. If the burn value is closer to 0, the color mapping is more exponential. If the value is closer to 1, the color mapping is more linear. So I think there are no reasons to not use Reinhard. If you want to use Exponential, then increase the burn value and control the brightness of the scene through the lights multipliers or the physical camera.
My recommendation is Reinhard with a low burn value, maybe .35.

I'll send you the test render and the fixed scene tomorrow.

Best

Re: what's this?

wow, nice! thanks alot FPEDROGO! i never realized those were the problems, i was trying to use setting from a 3ds max video i watched but i guess it doesnt work so welll for sketchup when it comes to doing tests. thanks alot bro your a life savor!
