Tutorial 3 Assets Problems with: rootNode.addLight(sun);

Troubleshooting graphics
1

I get the following error dump (in JME3) when running this tutorial (copied unmodified from the tutorial). To try to locate the problem, I have deleted most of the code and added back parts at a time so now the teapot, wall and text appear, but on adding the last line rootNode.addLight(sun); the blank scree appears for three seconds and then the error occurs.

Any suggestions appreciated.

well that too bad because errors seems to be on line 292 and 305, and are in the part you removed

Ooops, sorry, yes. I thought 300 odd lines were a bit long. Here they are:

#ifndef VERTEX_LIGHTING

290 float spotFallOff = 1.0;
291
292 #if VERSION >= 110
293 // allow use of control flow
294 if(g_LightDirection.w != 0.0){
295 #endif
296
297 vec3 L = normalize(lightVec.xyz);
298 vec3 spotdir = normalize(g_LightDirection.xyz);
299 float curAngleCos = dot(-L, spotdir);
300 float innerAngleCos = floor(g_LightDirection.w) * 0.001;
301 float outerAngleCos = fract(g_LightDirection.w);
302 float innerMinusOuter = innerAngleCos - outerAngleCos;
303 spotFallOff = (curAngleCos - outerAngleCos) / innerMinusOuter;
304
305 #if VERSION >= 110
306 if(spotFallOff <= 0.0){
307 gl_FragColor.rgb = AmbientSum * diffuseColor.rgb;
308 gl_FragColor.a = alpha;
309 return;
310 }else{
311 spotFallOff = clamp(spotFallOff, 0.0, 1.0);
312 }
313 }
314 #else
315 spotFallOff = clamp(spotFallOff, step(g_LightDirection.w, 0.001), 1.0);
316 #endif
317 #endif

Looks like your card doesn’t support the VERSION glsl macro…which is weird to be honest…
It seems to support opengl2.0 though.
Maybe try to update your drivers

The GLSL 1.10 specification (which this card claims to support based on the provided log) requires VERSION to be defined with constant 110. Looks like a non-compliant driver …
