переношу custom hlsl с ue5 на ue4. Вот этот код работает: рас Код: time=time2; float N = N1; float id=id1; float mr=0-r; float lat=id/N180-90+id/Npi2+time; float lg = id/N360-180+id/Npi2+time; float x = (r+id/Nrh) * cos(lat)cos(lg); float y = (r+id/Nrh)cos(lat)sin(lg); float z = (r+id/Nrh) sin(lat); pos.x=x; pos.y=y; pos.z=z-r/2; float3 vel = float3(0,0,0); vel =normalize(TP-inpos)5; if (length(inpos-TP)<(450+time)) { pos= inpos + vel; } а этот выдаёт ошибку два Код:* time=time2; float N = N1; float id=id1; float mr=0-r; float lat=id/N180-90+id/Npi2+time; float lg = id/N360-180+id/Npi2+time; float x = (r+id/Nrh) * cos(lat)cos(lg); float y = (r+id/Nrh)cos(lat)sin(lg); float z = (r+id/Nrh) sin(lat); pos.x=x; pos.y=y; pos.z=z-r/2; float3 vel = float3(0,0,0); if (length(inpos-TP)<(450+time)) { vel =normalize(TP-inpos)5; pos= inpos + vel; } три Цитата:* The Vector VM compile failed.
