Can Transparent BSP be done

ehrinmanske

So I have a texture that I want a part of it to be transparent for a see through glass effect, but not sure if it can be done directly applied to the BSP geometry of a level. I've gotten some suggestions to use a static mesh and replace the BSP with it, but I was hoping there would be an easier way. In unlit mode, the transparency shows up just fine, but no such luck in lit mode. Is there something that needs to be changed with the lighting to make this possible? Any feedback on whether or not this can be achieved being applied directly to the BSP would be great.

You can do this but there are various things to keep in mind and limitations.

Bottom line, use a mesh. Using a mesh is the easier way long term.

Alrighty then. I guess I'll scrap the idea if the only way to do it is by using a mesh.

what do you have against just using a mesh? bsp is pretty much only used for blockouts now in udk

Alrighty then, so it cannot be done, got it. Thanks guys

Grab a material in UDK that is transparent and apply it to a BSP.

That causes you to look into the void if using cubes. Planes have a higher chance of causing BSP errors. Both planes and cubes cause problems with shadow casting and such. Neither allows for various properties to be set, such as translucency sort prio.

In general there are only cons, no pros. So use mesh.

It's as easy as converting a brush to a mesh anyway, so it's not like it's much hassle
