Step by step Ambient Occlusion help

#1

I am setting up render layers for composite, and I need to set the ground not to self-occlude. I know I have to make an attribute named miLabel, but I need to know step by step which values to set where. Anyone wants to help??

#2

I fixed it:-D

Top Marks for most informative thread of the year :stuck_out_tongue:

Care to divulge? App used; what solution was to the problem (in case anyone else is having this question)

Bad etiquette sir

Wow, I am sorry that I do not follow the etiquette, I guess I was not aware of this, I am quite new to this forum. I haven´t gotten any answers to my post, so I just assumed that this was not of interest. But I got into the shape node of the object that I did not want to self occlude. Then in the attribute editor, enter the attribute tab, click add attributes. Call the attribute miLabel, set the min value to 0 and the max value to 1. Now this attribute shows at the end of where you´ve got your x y z attributes etc. THEN, make sure that the id nonself area in the mib occlusion shader is set to 1 aswell, and this should make your object not self occlude.

Happy to share, even happier to get responses;-)

This is in maya 2011. I set up the ambient occlusion by assigning a surface shader to an object. then connect a mib ambient occlusion shader from the mental ray shaders to this surface shader.

I am not a sir;-)

Thanks for the share, I was being slightly tongue in cheek with my post but tone is hard to detect.

I just think it’s a good idea if you manage to answer a question yourself to share with others what your solution was. Otherwise it comes across as being a bit selfish. (I’ve been guilty myself in the past)

Anyway good to see your solution and sharing.

p.s. sorry about the gender confusion :slight_smile:

That is ok, I´ll of course take my time to share from now on, I completely see the point since this is a forum that should be based on this idea:-) I am a newbie, and I guess sometimes I´m a bit self concious aswell, and think that there is really nothing that I can help people in this forum with, most people here do awesome stuff:-))
