The sky is obviously burned out, however I am not able to make it work well. I tried to move it down, change the saturation, multiplier etc. It is a HDRI placed as a 360 environment. Please note the shift of background behind the transparent sails in relation to the rest. Any clues?
Also about the water surface - I used glass material with displacement but could not find bump map. Any hints? Maybe there is a better cycles material to model it?
Other comments would be appreciated as well.
Some feedback:
It is way faster than I would expect even on my very slow laptop.
From time to time I get the image in pink shade after meddling with environment HDRI. Switching to wireframe and back to raytraced restores the correct image though.
This generally gets better with the Skylight intensity set lower.
If you are using glass or plastic for your sails you could change the IOR to 1.0
@andy recently added bump maps for glass and plastic, but I haven’t had time yet to integrate those changes into Raytraced. Could you send me the model so I can investigate and tell better what is going on? If it is a larger file you could use Rhino - Upload to Support with nathan@mcneel.com set to recipient. I can give you better info when I see the data of the model.
Hmm, that sounds odd, I’ll try to keep an eye open for this, see if it happens in my testing.
@killwater, just FYI that I’ll be on vacation from Thursday onward until the end of this month, so if you manage to send me the file during that time I’ll be able to give you more info in begin of August.
Hello everyone. I will try to send it later in the evening. @nathanletwory there is no hurry so some comments in August would more than enough.
The magenta shade I was talking about before:
Hello @killwater . I received your file, but I have trouble opening it properly. The file seems to be linking in block definitions from other files, I suppose they are not important for the test?
The magenta tint means either missing texture file, or too many float textures (HDRi textures). I’ll investigate further.
I do see trouble with loading the materials though, I’ll be checking this with @andy.
Hello
You can ignore the missing blocks as they are just little equipment objects on the deck.
As for the magenta issue please note that no changes to the model itself are required to get this effect. It just happens from time to time when switching modes or especially when modifying the environment (it is enough sometimes to change one parameter to trigger it). This happens several times per day.
it is enough sometimes to change one parameter to trigger it
This would mean float texture limit on GPU reached. I will have to revisit the texture management code for Raytraced when I get back from holiday begin August. In the meantime, could you run an experiment for me? Use RhinoCycles_SelectDevice and enter 0 for device. This will select the CPU for the current Rhino session (i.e. doesn’t stick after exiting the program). Once done set viewport to Raytraced and see if the magenta appears on frequent skylight texture changes. Please report.
