Hoofdstuk 52Render

De volledige naslagtabel: render engine, sampling, performance en Cycles

De Render Properties-tab (renderinstellingen) bepaalt hoe Blender een beeld berekent: welke render engine, hoeveel samples, welke apparaten, en tientallen instellingen die alleen zichtbaar worden zodra je Cycles kiest. Dit hoofdstuk is grotendeels een naslagblad: elke instelling is rechtstreeks uit Blender 5.1 uitgelezen.

Wat deze tab doet

1/7

De Render Properties-tab (renderinstellingen) staat in de Properties-editor onder het camera-icoon. Alles hier bepaalt de render als geheel, niet de scene of één object: welke render engine (EEVEE Next of Cycles), hoeveel samples er gebruikt worden om ruis weg te werken, welk device (CPU of GPU) rendert, en performance-knoppen zoals tile-grootte.

Een deel van de panelen verandert mee met de gekozen engine: EEVEE Next toont andere opties dan Cycles. De tabellen hieronder bevatten daarom eerst de algemene renderinstellingen, en daarna apart de Cycles-specifieke instellingen (deel K gaat dieper in op wat elke Cycles- en EEVEE-instelling in de praktijk doet).

De drie knoppen die je in de praktijk aanraakt

4/7

Van de tientallen instellingen hierboven zijn er drie die je bij vrijwel elk project echt gebruikt. Eerst Render Engine: EEVEE Next voor snelle, interactieve previews en de meeste real-time-achtige werk, Cycles wanneer fysisch correcte reflecties, caustics of een langzamere maar preciezere render nodig zijn. Tweede: Samples, apart voor viewport en render — hoog genoeg om ruis weg te werken, niet hoger, want elke verdubbeling kost ongeveer een verdubbeling van de rendertijd.

Derde: Film > Transparent als je een render zonder achtergrond nodig hebt (bv. voor compositing), en Performance > Threads als je machine met andere software moet delen tijdens het renderen.

Denoising: minder samples nodig door te filteren

6/7

Denoising (ruisonderdrukking) filtert overgebleven ruis weg na het renderen, zodat je met minder samples toch een schoon beeld krijgt. Cycles heeft een apart denoiser voor de viewport (snel, minder precies) en voor de finale render (trager, gebruikt extra Data Passes zoals albedo en normal om details te bewaren). Zet denoising in de render altijd aan tenzij je zelf in de Compositor een eigen denoise-node met meer controle opbouwt.

EEVEE Next heeft zijn eigen Raytracing-denoiser die los staat van de Cycles-instellingen hierboven — de naam is gelijk, de instelling niet.

shot-render-denoiseHetzelfde beeld met en zonder denoising, bij een laag samples-aantal.

Zelf doen · 52.7

Zelf proberen: CPU naar GPU, en het verschil zien

7/7

Open het meegeleverde bestand, zet de render engine op Cycles, render eerst met Device op CPU en dan op GPU Compute, en vergelijk de rendertijd die Blender onderaan het render-venster toont.

1Open blends/demo_render_settings.blend.
2Ga naar Render Properties en zet Render Engine op Cycles.
3Render met F12, Device op CPU. Noteer de tijd.
4Zet Device op GPU Compute (System-tab in Preferences moet een GPU-backend hebben ingesteld) en render opnieuw.
5Vergelijk: bij een klein aantal samples is het verschil klein; bij honderden samples wordt het groot.

Gelukt als…Twee rendertijden die je kan vergelijken, en een render engine die voortaan bewust gekozen wordt in plaats van standaard te blijven staan.
