I'm trying to get this effect cast on a model in a render ( a la' Snake in MGS3 only not in realtime! smile.gif ).
What do you think the best way of going about it is? Using a texture effect with the actual spotlight itself? Or actually making tree/leaves geometry and sticking it in front of the light and raytracing? ( seems like the latter could be very slow to render ) I'm using Maya 6.0

    So I tried plugging a texture into the spot colour and also tried plugging it into the spot intensity:

    OK, so this is a 'card' held up in front of the spotlight with the leaf texture as an alpha channel:

    It looks a bit rubbish dontcha think?!

    In the past I've always just used a mask material in the light itself.

    My mate built this, is this anything like the effect you are after?

    If so, I can ask him on MSN later today.

    I think you just need more color variation in your texture map. To make that image I just made this image in photoshop with the stock leaf brushes and varying shades of grey.

    leaves.jpg

    I mapped the leaves image to the color of a spotlight, then on the file node for the leaves, I used the Gaussian filter set to max, to blur the hell out of the leaves. I had to tweak the UV repeat values and the level of blur, to get the look I wanted. It also helped to raise the light intensity quite a bit, so you got those nice hotspots. For the shadows, use a really low Dmap resolution like 100, with a high dmap filter size (4).

    Nice image Rick! Yes that's what I'm after. Yeah that's great Pyromania. Thanks for taking the time. I think you've got it. More effort on the texture is required! Thanks!

    nice pyro;) I had to make something similar a couple years ago and this tutorial by Neil Blevins helped me out out a ton...
