Material Problem (FIXED)

[TattieBoJangle]

Hi guys I am getting a problem with the material the textures go dark its strange it only happened when I used the scale tool to set all the models in that folder to the same size then when I went back they were all dark. If need be I can do a video showing step by step what happens

I removed the mesh files and done them again it has got something to do with the alpha if I set it to alpha reject it just goes dark and also it messes with the shadows video uploading.

There is a small issue with the shader and scale, anything scaled can have an issue with shadows which is what you are seeing here. Best solution is to bake your scale to mesh to the correct scale ( "bake button" in the translation panel) so that the engine sends the correct coord to the shader.
Small scale adjustment errors are not noticeable but the size change you used will introduce shader errors. We hope some day to be able to get around this

the alpha reject initialises a double sided feature of the material as most meshes that have alpha want to see the texture on the other side like a single sided plane for a leaf. This of course though has problems if there actually is another mesh on the flip side as it will try to shadow itself. i think this is what you are seeing. I feel we need an option for double sided in the material editor.

To help prove this, first save the material with alpha and then try and open the material file in a text editor and look for all instances of this line:

Code: Select all

cull_hardware none

use ctrl+f to find in a text editor and replace with this commented version.

Code: Select all

//cull_hardware none

Then save and reload the material by regenerating the material in the asset manager or reboot skyline.

If the mesh comes in correctly like when there is no alpha material applied, except there should be alpha for your walkways etc...

let us know how this turns out

On a side note we are going to add a double sided flag to the material editor.

Yea that didn't work lol so I just turned off cast shadows so that will do for now

thanks for testing so it is shadow related. Has the mesh got a plane on the opposite side of the road really close together? as this might cause it to self shadow as well.

Just had a look and you are right going to send you a pm
