Returns the number of draw calls that used GPU morph deformation in the last completed frame. Read the counter after Flip; submitting RenderWorld alone does not execute the frame. It reports main-colour draw calls only. This counts draw calls, not entities, vertices or targets. Compatible copies may share one instanced draw even with different expressions. Draws with no active morph weights do not contribute. The count is replaced each completed frame, not accumulated. Shadow and auxiliary view draws are excluded. Use with RenderCPUMorphedDraws to observe automatic path selection. GPU morphing requires a compatible morph_v1 material and at most 32 active targets. Combined morph-plus-skin draws blend mesh-space deltas before applying skinning. CPU animation sampling and base-geometry queries remain unchanged.
