Leonardo IA avis : images premium + battlemaps D&D + calculateur ROI gratuit

Vous cherchez un générateur images IA qui COMPREND vraiment ce que vous voulez?

Voilà le problème brutal: les générateurs images génériques (DALL-E, Midjourney) donnent du beau mais inconsistant. Vous commencez une campagne D&D, générez votre elfe mage... puis session suivante, c'est une autre personne. Vous payez $20-30/mois pour Discord (Midjourney) ou ChatGPT, faites des douzaines d'essais, puis finissez par commander un artiste quand même.

Résultat réel: coût = outil + temps d'iteration + artistcommand = €1,000-5,000 par campagne visuelle.

Leonardo AI change ça radicalement. Pas juste "générateur images". C'est plateforme créative complète: custom models (entrainez le style de YOUR codebase), inpainting (éditez maps without redraw), style reference (cohérence garantie). Pour créateurs D&D? C'est le game-changer.

Ce que Leonardo AI peut faire VRAIMENT

Leonardo n'est pas juste "image generator". C'est arsenal créatif spécialisé. Voici l'arsenal exact:

Capacité	Détails	Impact réel

Inpainting/Outpainting	Éditez areas spécifiques sans regenerate full image	Battlemap existante? Ajoutez rooms. Pas redraw from scratch.
Style Reference	Créez base map, appliquez aesthetic à toutes variations	10 donjons même vibe cohérente. Thematic unity.

3. Generate (20 sec) → review
4. If adjustments: use inpainting (add trap door, widen corridor, change lighting)
5. Export 2048x2048 PNG → import Roll20 → done
6. Total: 30-90 seconds. Compare: 6+ hours hand-drawing or $200-400 commission

WORKFLOW #2: Custom Character Model Training (30 MIN SETUP, INFINITE USE)

Scenario: DM has signature art style (anime-inspired, dark fantasy, Witcher-esque). Wants all characters matching.

1. Collect 15-20 reference images (your preferred D&D art style)
