PRV over a shadowed terrain

PRV over a shadowed terrain - 03/05/15 16:12

Hi,
I realized the prv entity values are lost when putting a terrain as ground. It seems they are taking their values from the shadowmap of the block below the terrain that is full shadowed by the terrain itself.

A block is not shadowed by a terrain.

I rather think that the entities use the terrain's own shadow map.

I can see a terrain casting shadows on blocks crazy Look at this:

Click to reveal..



I did some test and checked the terrain lightmap color by myself.

Click to reveal..

Code:
var my_floor_ambient ()
{
	if ( !me )
		return 0;
//	set ( my, LIGHT | UNLIT );
	vec_set ( &my->blue, COLOR_WHITE );

	VECTOR vPos;
	vec_set ( &vPos, &my->x );
	vPos.z -= 300 - my->min_z;
	you = NULL;
	var height = c_trace ( &my->x, &vPos, IGNORE_ME | IGNORE_MODELS | IGNORE_SPRITES | SCAN_TEXTURE );
	if ( HIT_TARGET )
	{
		if ( you ) // if you exits, is a terrain for sure
		{
			if ( you->lightmap )
			{
				BMAP *bmpSkin1 = ent_getskin ( you, 1 );
				var scale = bmap_width(you->lightmap) / bmap_width(bmpSkin1); //
				var format = bmap_lock ( you->lightmap, 0 );
				var cX = hit.u1 * scale;
				var cY = hit.v1 * scale;
				var pixel = pixel_for_bmap ( you->lightmap, cX, cY );
				COLOR col;
				pixel_to_vec ( &col, NULL, format, pixel );
				vec_set ( &my->blue, &col );
//				vec_set ( &col, COLOR_WHITE );
//				pixel = pixel_for_vec ( &col, 100, format );
//				pixel_to_bmap ( you->lightmap, cX, cY, pixel );
				bmap_unlock ( you->lightmap );
				set ( my, LIGHT | UNLIT );
			}
		}
		else // hit a block
		{
			reset ( my, LIGHT | UNLIT );
//			vec_set ( &my->blue, &hit.blue );
		}
	}
	return height;
}



and I use vecLight as ambient color into the shader
Code:
float4 color = float4(vecEmissive.xyz * vecColor.xyz, 0) + vecAmbient * vecLight;

Ccan you check your "Terrain lighting" setting in the map compiler? It determines if the terrain is included in the lighting process or not.

Hi,
Yes. The terrain lighting is activated. I changed nothing in the compiler settings. There are no dynamic lights in the scene. Just a single static light with high resolution flags set. The terrain and blocks lighmaps are created by the compiler.

Ok, can you then contact support and send them the project? We'll have to look into that.
