I am currently facing a problem of having the “OpenGL fatal Error” and not be able to render my animation. Basically I designed a new L-system rule and would like to make an animation of the transformation when changing the angle. However, the error stopped me from rendering

Does anyone know what is the penitential problem and is there any other way that I could render this thing in a less pain manor? I desperately need those render and seems houdini need a really powerful computer for rendering animation.
