2 weeks ago, I sent my client the application to review and approve it, today they gave me the OK to compile the final version, but suddenly I get this, and part of my plane disappears to turn on lights (it’s an internal configurator of planes)
I need to fix this as soon as possible since I have to turn in the work
Hey @MLB ,
This seems related this this:

bug
area: graphics
Activating VSM shadows breaks up in default lit shader (without clustered lighti… ng)
# Error log
``` terminal
ERROR: 0:855: 'getShadowCoordPersp' : no matching overloaded function found
850: getLightDirPoint(light4_position);
851: dAtten = getFalloffLinear(light4_radius, dLightDirW);
852: if (dAtten > 0.00001) {
853: dAtten *= getSpotEffect(light4_direction, light4_innerConeAngle, light4_outerConeAngle, dLightDirNormW);
854: dAtten *= getLightDiffuse(litShaderArgs.worldNormal, dViewDirW, dLightDirW, dLightDirNormW);
855: getShadowCoordPersp(light4_shadowMatrix, light4_shadowParams, dLightDirW);
856: float shadow4 = getShadowSpotVSM32(SHADOWMAP_PASS(light4_shadowMap), dShadowCoord, light4_shadowParams, 15.0, dLightDirW);
857: dAtten *= mix(1.0, shadow4, light4_shadowIntensity);
858: dDiffuseLight += dAtten * light4_color;
859: dHalfDirW = normalize(-dLightDirNormW + dViewDirW);
860: dSpecularLight += getLightSpecular(dHalfDirW, dReflDirW, litShaderArgs.worldNormal, dViewDirW, dLightDirNormW, litShaderArgs.gloss, dTBN) * dAtten * light4_color* litShaderArgs.specularity;
```
### Steps to Reproduce
1. Add any light to scene.
2. Change shadow type to any `Varience Shadow Map` type.
3. getShadowCoordPersp is broken and objects with shadows are invisible.

Please see if the workarounds work for you till we fix this. Thanks.
Just to confirm - are you using VSM shadows, and clustered lighting is disabled?

I also notice that in the editor, most of the parts of my plane are not shown. This used to work OK

In version 1.61.3, I don’t have this error, PLEASE, don’t remove this version, until you fix the error.
As a temp workaround for the Editor, add this to the end of the URL:
?use_local_engine=https://code.playcanvas.com/playcanvas-1.61.3.js
eg
https://playcanvas.com/editor/scene/1004487?use_local_engine=https://code.playcanvas.com/playcanvas-1.61.3.js

The interior version is about to be updated to a new version that includes night lighting, and that is where I got the error

We’ve released 1.62.2 to the Editor which fixes the crash in the viewport but the shadows don’t look correct (see 1.62.2 VSM shadows from spotlights have no blur · Issue #5286 · playcanvas/engine · GitHub )
Please select 1.61.3 for publishing and the Editor settings (for the launch tab) for the short term while we investigate this issue
