Hi @Evgeni_Popov @nasimiasl , i want to draw multiple circles on the sphere when clicking the surface, could you please give some help?
To make multiple circles i found the RTT solution ([NME] Is interactable shader available in NME?).
To draw a well circle on sphere i found the CustomMaterial (vPositionW) solution in this question page.
But when i trying to use them together, i stuked. It seems the effectWrapper can not be used with CustomMaterial(ERROR: 0:8: ‘vPositionW’ : undeclared identifier)
