Rendering problems with lit mode
Hello,
I have installed and built the unreal 4 engine editor from source (with no
errors), and I am attempting to trial it. Firstly, since mesa still hasn't
implemented openGL 4.3, which Unreal Engine requires, I am running Unreal
Engine in openGL 3 mode. My graphics card is AMD HD 5570, Redwood, which wi=
ll
in the future receive openGL 4.3/4.5 support. So until that happens, I was
planning to just run Unreal Engine in the openGL 3 mode. However, when I run
openGL in that mode, it starts up without error into the project browser, b=
ut
when I create a project, the rendering of the game objects are horribly wro=
ng
(see attachment). It is fine when the scene is unlit; it is only wrong with
lighting. When the viewport is in lit mode (the one with the problems), it
floods the console with this message:
EE ../../../../../src/gallium/drivers/r600/r600_state_common.c:799
r600_shader_select - Failed to build shader variant (type=3D1) -1
I looked up the problem online, and it is a problem on the driver end, not =
on
Unreal's end.
