As you can see in this link, rendering was done using Blender 3D and its rendering engine called Cycles. All things visible on it are actually real 3D models (except the man on the right, two rose plants and the small greenery in the lower edge of the picture, pasted in using GIMP). As plants consist of tens or hundreds of thousands polygons, they do affect rendering time significantly. Fortunately, Cycles can run on CPU or GPU (if there is any compatible in the computer) and I am using GPU (AMD R9 380 card) most of times getting render times almost 4X faster than running it on CPU (old AMD Phenom II 1055 X6). Trees and ivy are large models (as regards the polygon count) but the most polygons are usually created for the grass. It is so called particle system (used also for creating fur, hair and other stuff in Blender) when real geometry is produced during the rendering process (something like nXt trees, shown as wire in drawing but converted into geometry just before rendering). That particle systems are capable of producing millions of polygons. For some reason that method keeps memory usage low so big areas can be covered without the risk of possible memory overflow. Ah, the base building model was created in Spirit, my main architectural CAD, exported to Blender using Collada output. Finally, time needed for this image running on GPU was about an hour and half for 1920X1400 resolution. After that, another hour in GIMP for composing additional plants and entourage described above as well as for sign and vignette effect.

Can you explain how you do your site adaption please? is it all PS or in NXT? I do a lot of plants in NXt and it kills rendering time.

Questions for nxt render for autocad
Good day everyone,Can anyone here help me with these issues i keep having with nxt render for autocad ?1. How do you bring in textured models into autocad ( 3ds and obj) without losing their textures or having to re-assign them.2. How do you move these objects from place to place without experiencing viewport refresh sluggishness in the autocad viewport ?3. How do you add dirt to fabric textures for rendering.4. How do you avoid repeat patterns in textures for rendering ?See More
