Images do not properly generate in ComfyUI + Krea2

My prompt is: Epic high-fantasy concept art, ultra-detailed. A road crossing golden plains leading toward a colossal dwarven mountain hall entrance recessed into themouth of a giant cave. The whole entrance along with its fortifications is recessed into the cave. Grand fortifications resting on the sides of the cave. In front of a massive square gate is a large tiled ceremonial platform covered in intricate golden and silver inlays, clean, polished, and well maintained. From the platform descends a broad V-shaped arrangement of stone stairways and terraces, with a wide central staircase. On both sides of the gate stand large statues sculpted from obsidian and marble that look like person in heavy armor, with glowing crystals embedded into armor, casting an eerie menacing aura. High battlements crown the fortified gate, with watchtowers, patrol platforms, armed sentries, banners, and active defenses overlooking the distant plains. The architecture appears created by a very powerful and ancient dwarven kingdom, continuously improved over millennia by master dwarven stonemasons. Immaculately maintained stone, polished metal inlays, fresh carvings, active crystal lighting, ceremonial banners, dwarven symbols, clean stonework, dramatic atmospheric perspective, cinematic composition, epic scale, realistic materials, highly detailed, masterpiece. I wasted whole afternoon trying to correct this issue. Some versions of this prompt actually generate proper image, but some result in either attached image or full on black image. I use default template for Krea2 Turbo from ComfyUI with these alterations: I disabled prompt enhance as I dont know what exactly it alters, and I want to achieve specific image. LLM max token is set to max (32768), because whatever. I have 2x XFX Radeon RX 7900 XTX with Corsair HX1500i 1500 W PSU. Both gpu's were tested in games, OCCT and normal chat LLMs without any issues (so far) so I don't think it's hardware issue or not enough power. I'm new to this so it might be some stupid mistake, but I have no idea what is wrong. submitted by /u/Hiranus [link] [comments]
