In my mind all this problems does not apply to the renderer itself/
Render Engine it is mainly more or less comfortable environment only for simple pressing button /Render/:)
90% of the whole work, this is softwares, in which the work is done /Cinema, 3d max, Photoshop, Maya and etc./
Placement of the light source in the scene, which HDR to put in environment slot, selection and editing of textures and materials, modeling /which renderer to do has nothing to do/,
It is not determined by the renderer, but determined with the taste, talent and technical skills in this software , by the current User///
In other words, For "Pink Pony" will have explain to first the basis of work in current 3d
software, Modeling, Compositing Software and etc, and finally to show where the button "RENDER" exist:)
This well-known problem for today, when everyone to knows how to download full ready models of chairs from internet and beautifully their spread,---- by clicking on button, suggests that to get good results///
Nothing to do///
