ulf.schroeter Posted October 15, 2010 Share Posted October 15, 2010 Hi UNIGINE, do you have a tip for convincing wet surface rendering of streets during/after rain fall. Wet surface darkening and coarse environment (e.g buildings, cars) and car/street light reflections on the road surface are the most important requirements. Variation of specular/environment reflections on the street to simulate water puddles on uneven road surface would be great. Some kind of additional texture animated rain drop effect would be perfect :) Any ideas would be helpfull Link to comment

Guest extaliones Posted October 18, 2010 Share Posted October 18, 2010 To reach this effect you can use particles and materials with reflection. For road you can use the material for plane surfaces with reflection property (mesh_reflection_2d_base). Use particles for splashes and transparent particles with refraction to simulate the distortion on the road surface. Also you can add more lights(which is not expensive, it can be spot or deffered lights) For other surfaces (buildings and etc.) сustomize specular and diffuse parameters to illuminating an objects.

ulf.schroeter Posted October 18, 2010 Author Share Posted October 18, 2010 Good ideas, thanks ! Link to comment
frustum Posted October 18, 2010 Share Posted October 18, 2010 This can be achieved as post processing material. Deferred buffer is wide now and contains depth, normal and diffuse information. So we can simulate water drops, wet color transformation and fake screen space reflection. We will provide such post material soon. Link to comment

frustum Posted August 1, 2011 Share Posted August 1, 2011 post_filter_reflection is ready. But Crytek was first. Link to comment
ulf.schroeter Posted August 1, 2011 Author Share Posted August 1, 2011 post_filter_reflection is ready. But Crytek was first. Great work Alexander ! But seems to be quite performance intensive according to FPS drop between non-reflection and reflection version Link to comment
patrick.voelz Posted September 27, 2011 Share Posted September 27, 2011 Indeed, the frame drop for this effect is pretty huge. Link to comment
steve3d Posted September 28, 2011 Share Posted September 28, 2011 how to use this filter? there is no document for this filter. how to specify the objects with reflections? Link to comment
manguste Posted September 29, 2011 Share Posted September 29, 2011 Just like other postprocess materials. I will add a full description in a day or two. Link to comment
manguste Posted October 6, 2011 Share Posted October 6, 2011 Added. Indeed, the frame drop for this effect is pretty huge. Yep, it is pretty heavy. But you can decrease the number of rectecting material, the number of samples and the step. That would alleviate the rendering load. Link to comment
