Why do hair particles disappear in adaptive render?
Strand render and adaptive render both display the same result. Also, hair converted from curves with the Hair Tools by bartoszstyperek doesn’t show up at all; appearing completely invisible in final render.
How to remove hair particles from render and viewport?
Although the viewport softmax is 7, you can type 9 directly. On the hairtest file, reducing the hair steps to 7 makes it render correctly, but also reducing the count of children, or changing the children from interpolated to simple. In the hairfromcurves file though, only reducing the steps seems to work.
How to hide particle emitters in viewport without hiding particles?
To exclude the emitter from the render without hiding the particles, disable Emitter in Particle settings > Render: This is already disabled in your file. To hide the emitter in the viewport without hiding particles, see Is it possible to hide particle emitters in the viewport without hiding particles?.
Why are the particles hidden in the render?
This is because the particle emitter is hidden in the render: Particles inherit the object level properties of the emitter, so hiding the emitter object will hide the particles. To exclude the emitter from the render without hiding the particles, disable Emitter in Particle settings > Render: This is already disabled in your file.
How are hair particles created in second blend?
Second blend has hair particles created from curves with the hair tools mentioned above. First case has the hair rendered only partially, second case has completely missing hair. UPDATE: The problem is now fixed now thanks to Wo!262’s suggestion.
Is the hair subtype supported in Radeon ProRender?
Out of Emitter particles, ‘Halo’ is the only subtype (‘Render As’) supported. in viewport, the Blender can hide the rendered halo particles beneath the UI particles. In such case, you can adjust the Size of the particles in the Viewport particles settings panel to be less than Scale in the Render panel: Hair is fully supported by Radeon ProRender.
