I came a cross a what ever to this add-on https://developer.blender.org/T35069
It lets you “snap Reflection” - align light to exact place where you need reflection.
Seems to me quite powerful tool for product designers to light object in easy way.
@pitiwazou: I used the same add-on (post 2015/5/12). Hmmm …
I tried point, sun, area, object lights and I can’t confirm that result.
I tried persp and ortho view - seems to me OK.
Now I tried Spot too and it goes somehow quite OK. I just noticed - lamp is not going always in normal direction, but probably it is correct to result wit reflection on touched place.
I’m not good for that, but probably its the right angle to get rays into a camera.
I mostly tried live render (shift+Z) just to place reflection and it seems to me it works.
Hi there! I’m the author of this thing, thanx for checking this out
I am aware this is very rough in places and I am planning a second round of fixes / enhancements for the near future… also open for suggestions…
@pitiwazou: there is a shortcut that toggles the orientation: LEFT_ALT while dragging --> could you check if this works for you? @vklidu: there is an option “Bend towards diffuse shading”: if you turn this up to 1 it will point in the direction of the normal (which gives maximum reflectance for diffuse shaders), otherwise it will point to the reflectance vector (which obviously gives the maximum of very shiny shaders) --> could you check if this works for you?
again: thanx for checking this out! @RickyBlender: meant to be installed as an addon (e.g. via User Preferences) @eppo: yep, I recall there was a change in the py API recarding ray_cast, will post a working version (also including some other changes) in a couple of days…
