How hard could it be ?? Although labelled as a DS model, bust and plinth were also supplied as OBJs, without MTL. I soon discovered the supplied 'Diffuse' and 'Bump' maps were a scatter of fragments that bore scant resemblance to the figure until applied. After wrangling free UV Mapper Classic, I accidentally generated a square texture map I could navigate. I belatedly discovered that mapping a model is not sufficient, you [b][i]also [/i][/b]have to save that [b][i]mapped [/i][/b]model so map and mapped mesh align. Sadly, the map was was squashed sideways, making eye-balls and pupils egg-shaped. After several tries, I found that re-sizing map at 2w:1h made the eyes and pupils 'round enough'. I tried painting by eye with free Irfan View ('IV'), was 'off' just enough to look silly. IV does not support 'layers' per eg Photoshop, so I could not use the map as a guide to build concentric zones. After some head-scratching, I wondered if I could use IV's 'water-mark' tool, which overlays one pic with another. Scaling and degree of 'marking' adjustable... The existing textures were mapped, so did not tile. I soon found a nice 'Rock High Res.jpg' with similar hue to let me continue. After several attempts, I managed to overlay this texture with barely visible map. But, again, my hand-painted map was just 'off' enough to look silly. Specifically, pupils did not align with their estimated texture. Time for Plan_B: If I could separate the eyes' irises and pupils from the rest of bust, I should be able to paint them more convincingly. A huge fight ensued with my ($$) TurboCad_2016. First, I had to 'explode' the OBJ from a single surface to a polygon mesh. Then, I began carving at bust, shifting my off-cuts to a 'hidden layer' until only the eyeballs were left. Unfortunately, each such scrap would become a sub-object, and we were talking dozen. Worse, the 3D Slice tool ran into same problem as a decade ago, TC suddenly deciding the remaining mesh was not suitable for Slicing or any other 3D Boolean.... I re-started several times, each one making fewer and fewer cuts, but I could not isolate the eye-balls before the Booleans 'locked up'. Then, a light-bulb moment: Perhaps the eye-balls were already 'grouped' ? Restart, explode, export as modified OBJ, check... Aha ! This time, the eyeballs appeared as individual 'groups'. Into UV Mapper Classic, where map 'tiled by group' now has the bust with two stand-alone round eyeballs... Save map, save mapped mesh. Several tries later, I've applied rock texture, yellow iris, black pupil to this map and the figure looks nicely ominous... ( Click to enlarge...)
