I have received your resource files for full evaluation and have detected an alpha-based image configuration combined with append-layer based shader attachment. Based on the provided files, here is my defect report: By creating and attaching multiple shaders onto the same "head_diff_000_a_whi" texture of the player model you are inducing depth-fighting between the bart and the face textures. It looks like a coding error in your script due to COPY & PASTE. In order to focus your eyes for critical reading, take a look at line 348 of example.lua: engineApplyShaderToWorldTexture(shader,clothes_ID[7]["face"][1],thePlayer, true) In this line you are using the "face" texture. Are you meaning to use the "beard" texture instead? If you are, then you can fix easily fix this issue by chaging the string and making sure that each shader points to only one texture. In case you are not, there is a fundamental flaw in your design that is caused by misunderstanding how the GPU works and how MTA is utilizing it. By using append-layers and enabling depth-testing, the GPU is attempting to redraw the beard onto the original model BUT this is not stable because of mathematical inprecision. Your textures will start to flicker or one will hide another. So how to fix this defect? Instead of creating two shaders that draw onto one texture, I recommend you to off-screen combine the textures and then apply them to a shader. You can use the dxCreateRenderTarget, dxSetRenderTarget, dxCreateTexture and dxDrawImage functions to create a drawing surface (render target), layer the face + beard onto each other and then use the resulting render-target as texture in your shader. Do not forget to enable alpha for the render-target! Here is how a combine-stage of two textures might look like: local function renderCombinedTexture(tex1, tex2) local tex1w, tex1h = dxGetMaterialSize(tex1) local tex2w, tex2h = dxGetMaterialSize(tex2) local cw, ch = math.max(tex1w, tex2w), math.max(tex1h, tex2h) local rt = dxCreateRenderTarget(cw, ch, true) dxSetRenderTarget(rt) dxDrawImage(0, 0, tex1w, tex1h, tex1) dxDrawImage(0, 0, tex2w, tex2h, tex2) dxSetRenderTarget() return rt end You should use renderCombinedTexture in the onClientRender event handler to adhere to MTA's recommendations. If you have combined the textures and the combined texture does replace a predefined texture fully of the GTA SA DFF file, then I recommend you to set appendLayers to false instead. I was unsure how your system worked in my previous reply so I spearheaded a guess. But now with my actual analysis I recommend you to NOT use the appendLayers functionality. IMO it is a feature of MTA with very limited applicability. You seem to use weird global variables across your script. Take a look at the following line which repeats itself but seems to imply a contradiction: hat[thePlayer] = shader The global table is called "hat" but the function it is used in is called addFace or addBart. Could this be a variable misuse? I am looking forward to hearing back from you! ?

Yes. I do not like to start support requests through private messaging but continuing there is fine.

I did'nt understand anything.
