| Summary | 0006014: Arrayed version of fbo.drawbuffers doesn't seem to work | ||||
| Description | I'm using two version of the same code, the only exception being the the way fbo.drawbuffers are specified One has: fbo = gl.CreateFBO({color0 = blabla}) fbo.drawbuffers = GL_COLOR_ATTACHMENT0_EXT and it works ok Another has: fbo = gl.CreateFBO({color0 = blabla}) fbo.drawbuffers = {GL_COLOR_ATTACHMENT0_EXT} and then, the texture is becoming pitch black I put some LOG_L traces into bool LuaFBOs::ApplyDrawBuffers(lua_State* L, int index) and found out that despite "else if (lua_istable(L, index) && GLEW_ARB_draw_buffers)" check is successful, attempts to read the table content result in zero read items. I also tried to rewrite the function a bit to https://hastebin.com/irikoqucuy.pl Isn't successful either. I'm a bit lost why table content is empty... | ||||
| Steps To Reproduce | 1. Create a texture blabla 2. Create an FBO using "fbo.drawbuffers = GL_COLOR_ATTACHMENT0_EXT" 3. Render something into the "blabla" texture while having the gl.ActiveFBO(fbo ...) 4. gl.Texture(0, blabla) 5. Draw it to the screen somehow 6. Observe success. 7. Change "fbo.drawbuffers = {GL_COLOR_ATTACHMENT0_EXT}" 8. Restart widget/gadget, observe black screen instead of the supposed content of "blabla" | ||||

Here is the example gadget, where line 0000051 makes drawing work, and line 0000050 instead of 0000051 make it does nothing: https://hastebin.com/dovolekaze.bash |

No edit here :( Here is the example gadget, where line 51 makes drawing work, and line 50 instead of 51 make it does nothing: https://hastebin.com/dovolekaze.bash |
