If the platform doesn’t support a specific version of OpenGL, Unity will fallback to a supported version

-force-glcoreXY: XY can be 32, 33, 40, 41, 42, 43, 44 or 45 each number representing a specific version of OpenGL.

With this argument, Unity will detect all the features the platform support to run with the best OpenGL version possible and all available OpenGL extensions

-force-glcore: To use the new OpenGL back-end.

-force-opengl: To use the legacy OpenGL back-end.

It’s possible to start the editor or the player with OpenGL using the command line arguments: OpenGL core profile command line arguments Like the ES 3 target, this also scales up to contain all desktop GL versions, where basic shaders will support GL 2.x while shaders requiring SM5.0 features require OpenGL 4.2+.

#pragma only_renderers glcore: Only compile for the desktop GL.

#pragma target 5.0 // OpenGL ES 3.1 + Android Extension Pack, desktop OpenGL >= 4.2, DX Shader Model 5.0įor including and excluding shader platforms from using a specific shaders, the following #pragma only_renderers / exclude_renderers targets can be used:.#pragma target gl4.1 // Desktop OpenGL 4.1, SM 4.0 + tessellation to match MacOSX 10.9 capabilities.#pragma target 4.0 // OpenGL ES 3.1, desktop OpenGL 3.x, DX Shader Model 4.0.When using the existing #pragma targets, they map to following GL levels: Indirect draw (Graphics.DrawProcedural and Graphics.DrawProceduralIndirect).Compute shaders (as well as ComputeBuffers and “random write” render textures).The new OpenGL back-end introduces many new features (previously mostly DX11/GLES3 only): This target level requires at least OpenGL 4.1 or DirectX 11.0 Shader Level 5 on desktop, or OpenGL ES 3.1 + Android Extension Pack on mobiles. Therefore a new shader target level is introduced: #pragma target gl4.1. This means that all shaders that are configured to target Shader Level 5.0 (with #pragma target 50) will fail to load on OS X. However, as Apple restricts the OpenGL version on OS X desktop to 4.1 at most, it does not support all DirectX 11 features (such as Unordered Access Views or Compute Shaders). MacOSX OpenGL driver limitationsĪs a new feature, the OS X Editor and Standalone now support the new OpenGL backend, which enables the use of OpenGL 3.x and 4.x features such as tessellation and geometry shaders. The new OpenGL Core is used by default on MacOSX and Linux.

This scales from OpenGL 3.2 to OpenGL 4.5 depending on the OpenGL driver support. OpenGL Core is the new back-end capable of supporting the latest OpenGL features on Windows, MacOS X and Linux.

Unity linux no support for opengl 4.5
