From 58a6f0764916adecb71385cd43b917f1b708b334 Mon Sep 17 00:00:00 2001 From: Ton Roosendaal Date: Tue, 12 Feb 2013 15:51:05 +0000 Subject: Bug fix #34213 (2) Adding non-RGBA float buffers as texture crashes MipMap code. Images with less than 4 channels not supported (yet). Not sure if we ever should even... normals, Z, vectors, UV, Index, all don't like downsampling. --- source/blender/render/intern/source/imagetexture.c | 3 +++ 1 file changed, 3 insertions(+) (limited to 'source/blender/render') diff --git a/source/blender/render/intern/source/imagetexture.c b/source/blender/render/intern/source/imagetexture.c index 55dadc14989..2827f90e4b6 100644 --- a/source/blender/render/intern/source/imagetexture.c +++ b/source/blender/render/intern/source/imagetexture.c @@ -1042,6 +1042,9 @@ static void image_mipmap_test(Tex *tex, ImBuf *ibuf) IMB_makemipmap(ibuf, tex->imaflag & TEX_GAUSS_MIP); BLI_unlock_thread(LOCK_IMAGE); } + /* if no mipmap could be made, fall back on non-mipmap render */ + if (ibuf->mipmap[0] == NULL) + if (tex->imaflag &= ~TEX_MIPMAP); } } -- cgit v1.2.3
