When creating a new sphere mesh with high number of slices/rings the top and bottom parts of the generated sphere are removed. This happens because the triangles in those parts, due to high resolution, end up being very small and are removed as part of the 'par_shapes' library's optimization. Adding par_shapes_set_epsilon_degenerate_sphere(0.0); before generating the sphere mesh sets the threshold for removal of small triangles is removed and the sphere is returned to raylib correctly.

The example originally did not use textures but the glsl shader do mention them and try to use them. Should the textures be added to the model's materials or should they be removed from the shaders? |

Example - deferred rendering updated to work for both Desktop and Web (using GLES3).
This one example will require custom compile command:
emcc -o shaders/shaders_deferred_render.html shaders/shaders_deferred_render.c -Wall -std=c99 -D_DEFAULT_SOURCE -Wno-missing-braces -Wunused-result -O3 -I. -I../src -I../src/external -L. -L../src -L../src -sTOTAL_MEMORY=134217728 -sFORCE_FILESYSTEM=1 -sEXPORTED_RUNTIME_METHODS=ccall -sMINIFY_HTML=0 -sUSE_GLFW=3 -sFULL_ES3=1 -sASYNCIFY --shell-file ../src/shell.html ../src/libraylib.web.a -DPLATFORM_WEB
--preload-file ./shaders/resources/shaders/glsl100/gbuffer.vs@resources/shaders/glsl100/gbuffer.vs
--preload-file ./shaders/resources/shaders/glsl100/gbuffer.fs@resources/shaders/glsl100/gbuffer.fs
--preload-file ./shaders/resources/shaders/glsl100/deferred_shading.vs@resources/shaders/glsl100/deferred_shading.vs
--preload-file ./shaders/resources/shaders/glsl100/deferred_shading.fs@resources/shaders/glsl100/deferred_shading.fs
raylib for web will need to be built with these commands:
emcc -c rcore.c -Os -Wall -DPLATFORM_WEB -DGRAPHICS_API_OPENGL_ES3
emcc -c rshapes.c -Os -Wall -DPLATFORM_WEB -DGRAPHICS_API_OPENGL_ES3
emcc -c rtextures.c -Os -Wall -DPLATFORM_WEB -DGRAPHICS_API_OPENGL_ES3
emcc -c rtext.c -Os -Wall -DPLATFORM_WEB -DGRAPHICS_API_OPENGL_ES3
emcc -c rmodels.c -Os -Wall -DPLATFORM_WEB -DGRAPHICS_API_OPENGL_ES3
emcc -c utils.c -Os -Wall -DPLATFORM_WEB
emcc -c raudio.c -Os -Wall -DPLATFORM_WEB
