2 Question regarding shadow

[10shu]

Hi, Go to little quiestion about shadows in leadwerks.

1-is it possible to cast the shadow of an alpha test textures? i tried to look if they was a shader to apply in the shadow shader slot in the material editor. but didnt find a shader That would do that...

2-I have notice a lot of shadow glitch. (please check the screenshot below)
In my Project I have a multi level house and I can see some random artefact on the wall inside my house.
Those artefact disapear when I move the light on the room above the artefact but they usually re appear when I reload the map.
I can also sometime see some of those artefact appear when I add or move an object in the scene...
are those already being reported? is there a way to fix those or limit them.

 

Thank you

ten

The leaves shader in the vegetation is one of the alphamask shadows. I believe there is another one, but not sure what it is called.

1) The shadow shader you are looking for is the Shaders/Model/Shadow/shadow+alphamask.shader

2) Its difficult to understand the problem you are showing - it could very well be an issue with the model. May need the actual model to understand the problem.

could it be cause of those kind of thing? model inter penetration

What the difference between a normal shadow and a buffered shadow?
I ve fixed the issues at one place by switching the shadow from buffered to a normal shadow.
And the issues seem not to comeback at this place when I reload the game.

Ok the problem is resolved.
I switched all the light to shadow without the buffer and now it s all good...
