Hi Luis, GLES2 cannot use particles nodes, the colors are also a bit different than GLES3, no HDR and no advanced rendering features for spatialmaterials, lots of environment features are also missing. See more missing features here: godotengine.org/en/stable/tutorials/misc/gles2_gles3_differences
so at the actual stituation I do not plan to improve for GLES2, but if there will be a good demand from customers for gles2 then yes
