Your first path-traced frame
Empty network to a denoised Photon RTXPT render in ten minutes.
This guide assumes an installed and activated Photon RTXPT. Watermark mode works too — everything renders, watermarked.
Make some geometry
A Grid SOP as the floor and a Torus SOP floating above it. Nothing fancy — this scene is about light, not modeling.
Drop the renderer
Add a Photon RTXPT TOP from the OP Create dialog's Custom tab.
Point its Geometry parameter at the container holding both SOPs:
op('photon_rtxpt1').par.geometry = '/project1/geo1'You already have an image — the default camera orbits the scene bounds and a default dome light fills it.
Light it on purpose
Add a Photon Light COMP, type Area, and set intensity to
10000 lumens. Kill the default dome by setting the renderer's
Default Dome toggle off. One soft key from the left — already worth a
screenshot.
Give the floor a material
Add a Photon Material COMP, set Roughness to 0.15, and bind it:
op('photon_mat1').par.bindpaths = '*/grid*'The torus keeps the default gray; the floor picks up a soft reflection of it.
Let it converge
Stop moving the camera and watch the sample counter climb in the info overlay — the image resolves in a second or two. That's accumulation; it resets on any move and the denoiser hides the restart.
Where to go from here
Drop a Movie File Out TOP after the renderer and you have path-traced playblasts — accumulation makes still-camera exports look like offline renders.
