Indigo 1.1.8

[Big Fan]

ono there seems to be an issue with 'phong' not liking 'albedo' for a texture

AFAIK all the other mat types accept 'albedo' and 'phong' is happy with the rest of the texture types, just not albedo
--------
Edit: ok play time 95% done of 1.1.8 but not uv wraps stuff which I dont know enough about

attach is a very young and ugly render of glowing titanium (.nk) turbine...
---------
Edit2: indeed why it is was more of a mess than intended was cos I didnt realise I had some bugs in there - squashed those now - here is a better render

still very cool layer stuff ono

hi ono, i still getting this error:

Code: Select all

Error: IndigoDriverExcep: ObjectExcep: Tried to do a view-dependent subdivision on an instanced mesh. (subdivide_pixel_threshold > 0.0)

no subdivision anywhere in the scene.. in 1.1.7 was no problem..

... and you always will keep getting this error, because the view depended subdivision doesn't work for instances! set it to 0 and your instances should work fine. Each instance of a mesh is positioned somewhere else in the 3D space so for each one the view depended subdivision should be calculated different....

ZomB: would you tell me where to set it to 0?

hooray! thank you - a very useful post -peasants can be just adoreable sometimes no executions this week..dont expect promotion though

ok now here is my next question but useless ono can get off his butt and answer this one:
what happened to exponent maps?
there is no mention of these in the latest pdf
albedo, bump, displacement, emission...(exponent?)

Phong exponent is now a wavelength-independent material parameter. The manual is wrong on this one

This is a bug that i'll fix for the next version.

How do we do a dirty work around? And what casuses the problem? I was just about to mess around with shaders but this kinda stopped me

[carbon]

so i removed instances and got this:

I think there are some new shader bugs. I tried to use this shader from your 'shader tests' thread and I got an error saying that indigo could not find function 'eval'.

Code: Select all

def eval(vec3 pos) real : 
                     mul( 
                        fbm( 
                           mul(getTexCoords(0), 100.0), 
                           10 
                        ), 
                        0.001 
                     ) 

I'll run some more tests later to see if this was an isolated case or if it happens every time.

Ok I think this is the moment for:

I'll release 1.1.8 tomorrow barring any unforeseen issues.

i told you

[Big Fan]

@fused

@whaat also have the same problem with that shader - dont know why - however ono said that example was broken -guess it still is the anist one seems ok though
