got sort of a lighting question than a dynamic question but since this thread is all about my grass I figured id post here.
basically the grass has been set up, it is a very large grass scene btw. it dynamically moves with wind and is effected by characters. the grass has been cached and for the record is going to remain in its paint fx state and not be converted.
Up until now getting shadows to cast from the grass has been as simple as creating a light that creates depth map shadows. the shadows are casted on objects that have the use background texture.
we have completed several shots following the workflow of importing the grass file in the scene files. reconnecting the cache files. making sure the textures are use background and the lights are set up for depth map shadows.
now all of a sudden we are having some shots were there are no shadows coming up. we have checked all our workflow aspects as well as light linking, and checking the hypershade, etc etc. I currently don’t know what else to do and am in need of any possible suggestions someone might have. Please any idea will be helpful.
Also, on a more dynamic note. The cache files that are being create work correctly in terms of when they are connected to the node with in the grass system the grass moves the way it should. however on some renders there will be a hair system that for some reason remains static and doesn’t move. this is after scrubbing the timeline in maya to make sure all the grass behaved correctly.
Again please any help on either of these subjects is greatly needed and appreciated. thanks.
