Irrlicht Engine

I've recently sucessfully used it with Ubuntu 20.04 and an old NVidia card. Perhaps you want to give Ubuntu a try?

Btw: Are you using the proprietary drivers or are you using nouveau? Perhaps switching the drivers might help?

Hi, When using createScreenShot red and blue channels are mixed up in GLES2 (tested on Linux). I currently use a workaround in COGLES2Driver::createScreenShot by switching these channels back afterwards:           for(u32 x=0; x<ScreenSize.Width; x++){             for(u32 y=0; y<ScreenSize.Height; y...

Yes it's possible that I fixed this locally a long time ago and forgot about it.

Here's the ply: https://we.tl/t-Eb0I5DQLvr

Hi, since I updated my Irrlicht fork to the latest Irrlicht from the ogles branch I get an "invalid read" when testing with valgrind in the CPLYMeshFileLoader: Here's the diff: @@ -571,7 +572,7 @@ c8* CPLYMeshFileLoader::getNextLine()         StartPointer = LineEndPointer + 1;           //...

Yes it's with the newest ogles-branch. I think it makes sense to add it to Irrlicht. However I don't have an explanation for this. It's just the result of trial and error. There might also be a problem with the current emulator from Android Studio. Btw: IRR_OPENGL_HAS_glGenerateMipmap is defined in ...

Hi, there seems to be something wrong with glGenerateMipMap in COpenGLCoreTexture.h: In this line I get an GL_INVALID_ENUM error when I run this on linux or a real Android device. In the Android emulator I get an GL_INVALID_OPERATION . However the enum parameter is correct (GL_TEXTURE_2D). I noticed...

Hi, I've made my extension available at github: https://github.com/wolfgang1991/CommonLibraries Most interesting part for most people might be the SDFF (Signed Distance Field Font) implementation with some effects and support for arbitrary font transformations. New GUI Elements optimized for touch i...

I believe I found the solution: IVideoDriver::removeHardwareBuffer must be called to avoid the memory leak when deleting the meshbuffer. Btw: After looking at the code of CMeshCache::removeMesh I believe I found a bug. This function does not remove the hardware buffers when deleting a mesh: void CMe...

Hi, I'm wondering if the following steps would create a memory leak on GPU side: 1. Create an SMeshBuffer with some content 2. Use setHardwareMappingHint(EHM_STATIC) 3. Render it many times via IVideoDriver::drawMeshBuffer 4. Delete the SMeshBuffer I believe the Vertex Buffer Objects still persist a...
