How to get dynamic shadows from texture alpha channels

If you have a model that has both solid geometry and a texture with an alpha transparency such as a fence with solid posts and netting, you can get both to show in ArmA 2 (and 1) by using this simple method.

1. Create your fence in O2 with netting as usual ensuring the netting has an alpha channel. (Photoshop; save as 32 bit tga)

2. Create a shadowvolume lod for the post.

3. In the ShadowVolume Lod create a property called Shadow and give it's value as Hybrid. AFAIK Hybrid combines both shadowvolume and normal object shadows which incorporates the alpha textures as well. Then what do I know, I'm just a colonel... :)

Voila! It's as simple as that. Now you can create objects that have complex alpha textures and have the shadows as well

Yay its Colonel_Klink with useful info! Are you making any addons for Arma2?

Thanks Colonel_Klink for the nice tutorial, much appreciated.

Nice to see you in the forums also, now there is hope for ArmA 2 if OFP legends like you are returning :)

is there any way to increase the resolution on the alpha shadows?

so they dont look like this
